What is the molarity of a solution made by dissolving 58.44 g of NaCl in enough water to make 1.0 L of solution?
Divide grams (mass) by molar mass to find moles58.44 (g NaCl/L) / [22.99+35.45](g NaCl/mol NaCl)= 1.000 mol/L NaCl
What is the molarity of a 3.292 Liter solution that is made from 17.62 grams of NaCl?
A liter is equal to a dm3. So, we have 3,292 dm3 solution. We need the amount of the NaCl. It is m/M -> 17,62 / 58,5 -> approx. 0,3012 mol. So, the molarity is 0,3012 / 3,292 -> 0,0915 mol dm-3 .
What is the molarity of the solution made by dissolving 22.4 g of LiClO4 3H2O in 225 mL of water?
.62 M is the molarity of the solution made by dissolving 22.4 g of LiClO4 3H2O in 225 mL of water.
Which would form an electrolyte solution?
A strong electrolyte is an electrolyte that exists in solution almost entirely as ions. An example is NaCl. When NaCl dissolves in water, it dissolves almost completely to give Na+ and Cl- ions.
Does soap carry a charge?
Yes soap solution or any solution can be made to conduct electricity. But, when the solution is made of distilled water then electric conductivity is less compared to ordinary water. The conductivity of a solution depends on the purity of the water as electrical conductivity depends on the availability of positive and negative ions in a solution, and ordinary water contains a lot of salts i.e. NaCl which can split into NA+, Cl- ions, these ions can conduct electricity in water. But in distilled water, depending on the purity of the salts in the solution, electrical conductivity increases or decreases.
What is the volume of 3.0 M solution of NaCl made with 526g of solute?
Need to find moles NaCl. 526 grams NaCl (1 mole NaCl/58.44 grams) = 9.0 moles NaCl --------------------------------now, Molarity = moles of solute/Liters of solution or, for our purposes Liters of solution = moles of solute/Molarity Liters of solution = 9.0 moles NaCl/3.0 M = 3.0 liters in volume ---------------------------------
What is the molarity of a solution made by dissolving 58.44 g of NaCl in enough water to make 1.0 L of solution?
Divide grams (mass) by molar mass to find moles58.44 (g NaCl/L) / [22.99+35.45](g NaCl/mol NaCl)= 1.000 mol/L NaCl
What is the molarity of a 2.000 L solution thatis made from 14.60 g of NaCL?
Find moles NaCl first.14.60 grams NaCl (1 mole NaCl/58.44 grams)= 0.2498 moles NaCl================Now,Molarity = moles of solute/Liters of solutionMolarity = 0.2498 moles NaCl/2.000 Liters= 0.1249 M NaCl solution--------------------------------
What is the mass percent of the solution. if An aqueous NaCl solution is made using 138 g of NaCl diluted to a total solution volume of 1.10 L Assume a density of 1.08 g per ml for the solution.?
138 g NaCl 1.10 L= 1100mL 1100mL x 1.08g/mL = 1188 grams TOTAL 138/1188 x 100 = 11.6%
Is electrolytes made of NaCl?
Any solution that conducts electricity is called an electrolyte; salt water, also known as an aqueous solution of NaCl, is a type of electrolyte, although certainly not the only type.
What is D50.45 NaCl made of?
This is the code of a water solution containing 5 % dextrose and 0,45 % sodium chloride.
If you want to read the absorbance at 595nm of a protein solution mixed with the colorizing solution called Bradford reagent what is a suitable reagent blank?
a "blank" cuvette can be made with a sufficient amount of distilled water (assuming you're diluting your stock solution with distilled water).
What is the molarity of a solution made by dissolving 29.0 grams of NaCl in 150 ml of water?
29g/150*1000 is 193.333g. The molecular weight of NaCl is 58.433. Therefore 193.333/58.433 is 3.31 molar.
The sterile solution used to rinse contact lenses can be made by dissolving 400 mg of NaCl in sterile water and diluting to 100 mL. what is the molarity of this solution?
First, find the moles of NaCl. Because you have 400 milligrams of NaCl convert to grams by dividing 1000mg. 400mg/1000mg = 0.400 grams of NaCl. Now we need to convert to moles. For every mole of NaCl there is 58.44 grams. (22.99g Na + 35.45 g Cl) so using stoichiometry (grams cancel) I get .0068 moles of NaCl. Conver 100 mL to L by dividing by 1000mL. Therefore there is .001 L in the solution. Molarity is moles per Liter. So 0.0068 mols of NaCl / 0.001 L = 6.84 M
What is the molarity of a 3.292 Liter solution that is made from 17.62 grams of NaCl?
A liter is equal to a dm3. So, we have 3,292 dm3 solution. We need the amount of the NaCl. It is m/M -> 17,62 / 58,5 -> approx. 0,3012 mol. So, the molarity is 0,3012 / 3,292 -> 0,0915 mol dm-3 .
A solution is made by dissolving 17.52g of nacl exactly 2000 ml what is the molarity of this solution?
concentration or molarity = number of moles/volume number of moles (n) = mass in grams of nacl/relative atomic mass of nacl n=17.52/(23+35.5) n = 0.2994872 mol volume = 2000/1000 = 2dm^3 molarity = 0.2994872/2 =0.15mol/dm^3
Salt is made up of?
NaCl or sodium chloride NaCl is table salt
