What is the molar mass of CaCl2?

Calcium chloride/Molar mass
The molar mass of a compound is just the molar masses of every element in the compound added up. Since the molar mass of Calcium is 40.08 g and the molar mass of Chlorine is 35.45, it would be 40.08g+35.45g+35.45g (with 2 Chlorines according to the subscript.) That leaves you with 110.98 g.Sep 5, 2016

How could you prepare 250 ml of 0.20 M NaCl using only a solution of 1.0 M NaCl and water?

As a result, to prepare 250 ml of 0.20M NaCl, take 50 ml of 1.0M NaCl solution and add 200 ml of water.

How many moles of solute are in the solution?

The number of moles of solute = mass of solute ÷ molar mass of solute, where mass is measured in grams and molar mass (defined as the mass of one mole of a substance in grams) is measured in g/mol.

How many moles of HNO3 are in the sample?

Divide the amount of HNO3 by 63 to determine how many moles there are in the amount of HNO3 you are using for your calculations. For example, if there are 1,000 grams of HNO3, divide 1000 by 63; the result will be the number of moles contained in 1,000 grams of HNO3, which is 15.87 moles.
