The molar mass is the mass of one mole of a substance in g/mol. In order to determine the molar mass, you must know the chemical formula and have access to a Periodic Table. Let's use water as an example. The chemical formula for water is H2O. To find the molar mass, multiply the atomic weight on the periodic table in grams/mol for each element times the subscript for the element, and add the molar masses.
H: 2 x 1.00794g/mol = 2.01588g/mol
O: 1 x 15.9994g/mol = 15.9994g/mol
------------------------------------------------
Molar mass = 18.0153g/mol
What else can I help you with?
Which has more water potential a 0.6 molar solution or a 0.4 molar solution?
The 0.4 molar solution has a higher water potential because as the concentration of solute decreases, water potential increases. Water potential is a measure of the tendency of water to move from one area to another, and it is affected by factors like solute concentration and pressure.
What is a water hydrophilic?
Compounds that like water.
How do you calculate the equivalent weight of compound?
the sum of the atomic weights for all the atoms in the formula
Why and how inorganic compounds dissolve in water?
Inorganic compounds dissolve in water due to the water's polar nature. Water molecules attract and surround the ions or molecules of the inorganic compound, causing them to break apart. This process, called hydration, allows the individual components of the inorganic compound to be dispersed throughout the water.
Is a nonpolar compound miscible with water?
No, nonpolar compounds are typically not miscible with water because water is a polar molecule. Polar compounds dissolve in water due to the similar nature of their molecular structure, while nonpolar compounds do not have the same attraction to water molecules.
How water disssolves ion compounds and polar compounds?
Like dissolves like. Water is polar solvent and hence it dissolves ionic and polar compounds.
Which has more water potential a 0.6 molar solution or a 0.4 molar solution?
The 0.4 molar solution has a higher water potential because as the concentration of solute decreases, water potential increases. Water potential is a measure of the tendency of water to move from one area to another, and it is affected by factors like solute concentration and pressure.
What is a water hydrophilic?
Compounds that like water.
What releases ions when dissolved in water?
Soluble ionic compounds like NaCl, and some covalent compounds like HCl(g) which will dissociate in water.
How do you calculate the equivalent weight of compound?
the sum of the atomic weights for all the atoms in the formula
what compounds in the liquid stage can be considered an electrolyte?
generally ionic compounds like those compounds which dissolves into ions in water like NaCl,NaOH etc.
How do you make a 0.1 molar solution if you had a 1.0 molar solution to start with?
To make a 0.1 molar solution from a 1.0 molar solution, you would dilute the original solution by a factor of 10. For example, you could mix 1 part of the 1.0 molar solution with 9 parts of solvent (like water) to achieve a final concentration of 0.1 molar.
Is mineral water an element mixture or compound?
Mineral water contains other elements or compounds too. They contain elements and compounds like Sodium, magnesium,macro nutrients,calcium and other minerals. So mineral water is a mixture of compounds.
What type of compounds can dissolve in water?
Polar compounds, such as salts and sugars, dissolve in water because water is a polar molecule. Nonpolar compounds, such as oils and fats, do not dissolve in water because they are not attracted to the polar water molecules.
Do all compounds contain water?
No, not all compound contain water like carbon dioxide, it does have water in it
Why and how inorganic compounds dissolve in water?
Inorganic compounds dissolve in water due to the water's polar nature. Water molecules attract and surround the ions or molecules of the inorganic compound, causing them to break apart. This process, called hydration, allows the individual components of the inorganic compound to be dispersed throughout the water.
Calculate the percent by mass of water in the hydrated calcium sulfate salt?
Take the mass of the water lost and divide that number by the mass of hydrated calcium sulftate. Then multiply your answer by 100. For example: To find the amount of water, subtract the mass of the anhydrous sample from the hydated one like this: Mass of hydrated salt: 21.626 Mass of anhydrous salt: 21.441 21.626 - 21.441 = 0.185 (amount of water) To find the percentage of water, divide the water mass by the hydrated mass number: .185/21.626 = 0.00855 Now all you need to do is multiply your answer by 100 to get the percentage: 0.00855(100) = .8554% To see this last part algebraically, you can say, "what percent of the hydrated salt (21.626) is the mass of water (0.185)?" This would look like: x%(21.626)=0.185
