Total: 36

Calculate the mass of sodium acetate (CH3COONa) required to make 500 mL of 0.375 molar aqueous solution. Molar mass of sodium acetate is 82.0245 gmol–1.

Solution:

Molar mass of sodium acetate = 82.0245 gmol–1
Mass of CH3COONa required to make 500 mL of 0.375 M solution
=

0.375×82.0245×500

1000

= 15.38 g
