If 8.62 g of CuNO3 is dissolved in water to make a 0.500 M solution, what is the volume of the solution in milliliters?

Answer 1

molar mass CuNO3 = 125.6 g / mol

0.500 M = 0.500 mol / L

0.500 mol / L x 125.6 g / mol = 62.8 g / L

8.62 g x 1 L / 62.8 g = 0.137 L = 137 mls

or..

8.62 g / x L = 62.8 g / L

62.8x = 8.62

x = 0.137 L = 137 mls
