3
One liter of 5.0 M HCl contains how many moles of HCl? M = 5.0 mol= ? L = 1 L x = 5 mol

4
55mL of 2.4M glucose contains how many moles of glucose? Need to change mL to L M = 2.4 mol = ? L = 55mL 0.055L x = 0.132 mol

5
How could we make a 0.100M solution of CuSO 4 * 5H 2 O? Molar mass = 249.6 g/mol x = 0.100 mol 24.96 g

6
M is concentration in Molarity V is volume (can be mL of L)

7
How can we make 500mL of 1.00M HCl from 6.00M HCl? V 1 = 500mL M 1 = 1.00 M V 2 = ? M 2 = 6.00M x = 83.3 mL or 0.0833 L

8
What is the molarity of a 250mL solution containing 9.46g CsBr? Molar mass of CsBr = 213 g/mol 0.0444 mol CsBr 0.176M

9
** remember that solution is (solute + solvent)

10
What is the mass percent of a solution made from 199g of NiBr 2 in 5.00x10 2 g of water? Solution = solute + solvent Solute = 199g Solution = 500g + 199g = 699g (solvent) (solute) 28.5% NiBr 2
