What is the concentration of salt?

This is a very nonspecific question, but concentration is just the amount of solute in a solvent. Typically this is expressed in terms of Molarity.


Difference between normality and molarity?

Normality is another way to express the concentration of a solution. It is similar in many ways to molarity. The difference is that molarity is way to provide information about the number of molecules in a liter of solution and normality provides information about the number of reactive units in a liter of solution. Molarity is expressed in terms of moles of a compound per liter of solution. (Remember a mole is molecules) Normality is expressed in equivalents per liter. An equivalent can defined as the number of moles of "reactive units" in a compound. One equivalent can either react with or take the place of one mole of hydrogen ions.


What is the OH- of a 4.0 x 10-4 M solution of CaOH2?

The concentration of the OH- is 8.0 x 10-4 In terms of molarity, since the hydroxide is double that of the calcium, double the molarity of the solution.


What is the concentration of a solution in terms of solute per liter of solution?

The molarity of a solution is the number of moles of a solute per liter of its solution. The normality of a solution is the number of gram equivalent weight of a solute per liter of its solution. As I said before, and precisely, Molarity is moles of solute per VOLUME of solution!


The amount of solute dissolved in an amount of solvent is called the solution what?

The amount of solute per a given amount of solvent is called the concentration; if it is expressed in terms of moles per liter (which is what chemists usually work with) then it can also be called molarity.


What is the salts concentration?

This is a very nonspecific question, but concentration is just the amount of solute in a solvent. Typically this is expressed in terms of M (molarity) in moles per liter or just in grams per liter.You also should state of which salt the concentration is given.The third, though not preferable way is in % (grams salt per 100 grams of solution).


What is the pH of 7 percent NaOH solution?

How to work it out - Calculate the concentration of the solution in terms of molarity. Calculate the hydrogen ion concentration from the fact that multiplying the hydrogen and hydroxide concentrations (in mols per litre) will always give 1x10-14. Take the -log10 of the hydrogen ion concentration.



What is the amount of solutes in a given amount of solvent?

The term for a level of solutes in a solution is called the concentration. A "concentrated" solution has more solutes than a "dilute" solution.There are two related terms:The molarity or molar concentration expresses the mass of constituents per volume of solution.The related term molality expresses the mass of constituents per mass of solvent.


Is concentration typically given with the volume of solvent or the volume of solution?

The concentration of a solution is typically given in terms of the volume of solution, in liters.



What are dilute concentrated and saturated solution?

A saturated solution is a solution in which the solute has been dissolved to the point where if any more solute is added it would not be able to dissolve. Concentrated and dilute are relative terms where concentrated means more solute per liter of solution while dilute is less solute per liter of solution. Concentration is depicted by Molarity.


How can you convert moles to liters?

You cannot. However, you can change moles to moles per litre (molar, M), if you know what vilume you are making the solution to. If the volume you are making the solution up to is in millilitres, divide the moles by the amount of millilitres, and then multiply by 1000. This will give you a concentration in terms of molarity.


What is the difference between relative concentration and precise concentration?

Relative concentration gives you a comparison of two or more solutions, telling you which has a higher concentration of some solute than the other. Precise concentration would normally be expressed in terms of moles per liter, and it tells you the actual amount of a solute that is present in a given volume of solution.


You mix 15g of sugar in enough water to make 1 L of solution The concentration of this solution is?

15 grams sugar per liter is the concentration, in terms of mass per volume. To express the concentration in molarity (assuming the sugar is sucrose): 15 g sucrose * (1 mole sucrose / 342 g sucrose) / 1 L = 0.0439 M aqueous sucrose


What is the scientific term of concentration?

The amount of a substance per defined space. Concentration usually is expressed in terms of mass per unit volume.


How does the rate law show how concentration charnes affect the rate of reaction?

The rate is expressed in terms of concentration of the reactants raised to some power


What do the following terms mean - hypotonic isotnic and hypertonic solutions?

Hypotonic solution has a lower concentration of solutes when compared to the solvent. Hypertonic solution has a higher concentration of solutes when compared to the solvent. Isotonic solution has the same concentration of solutes as surronding cells.


What is the application of molarity?

Molarity is the number of moles of solute in per liter of solution. It is used to to tell you the quantity of a chemical that is dissolved in a solution. Conversely, if you dissolve some chemical in a solution, then you can determine the molarity and know something about how many molecules you are adding if you know the molar mass of the chemical. When designing or understanding a chemical reaction, it is much better to quantify the process in terms of the number of molecules involved in the reaction. Molarity is how you do that. Otherwise, describing chemical reactions and just measuring in grams of reagents gives no information of how much, in terms of number of molecules, are involved. That is why so much emphasis in chemistry is given to reaction balancing and molecular weight.


What terms describes a solution with a higher concentration of dissolved substances relative to another solution?

Hyperosmotic? The solution with the higher amount of solutes has a higher osmolality, thus, it is hyper-osmotic



How to make a standard solution?

A known quantity of a substance is dissolved in solution for a standard solution. This is expressed as units of mole per liter, moles per cubic centimeter, or in terms of that particular titration.


How does the rate law show how concentration changes affect the rate of reaction?

The rate is expressed in terms of concentrations of the reactants raised to some power.


How are volumes of hydrogen peroxide related to concentration of hydrogen peroxide expressed in percentage terms weight volume?

The strength of a solution may be described as a percentage or volume, where 1% hydrogen peroxide releases 3.3 volumes of oxygen during decomposition.Thus, a 3% solution is equivalent to 10 volume and a 6% solution to 20 volume, etc. Answer taken from Wikipedia 19/01/2009
