The compound K2SO4 has solubility of 15 grams in 100mL of water. How many milliliters of water are required to dissolve 53 grams of K2SO4?

Solutions

Expert Solution

15 g of K2SO4 require 100mL of water

Therefore 53 g of K2SO4 will require 100 mL x 53 g / 15 g of water = 353.3mL of water

The volume of water required to dissolve 53 grams of K2SO4 = 353.3 mL

ALTRNATE METHOD

Mass of K2SO4                                 Volume of water

15 g                                                          100mL

53 g                                                             x

      = 353.3 mL

The volume of water required to dissolve 53 grams of K2SO4 = 353.3 mL
