Answer: -

16.39 mL is the minimum volume of boiling water needed to dissolve 0.200 g of phenacetin

Explanation: -

Mass of phenacetin = 0.200 g

The solubility in boiling water of phenacetin is 1.22 grams of solute per 100 milliliters of water.

Thus, minimum volume of boiling water required to dissolve 1.22 g is 100 mL

Minimum volume of boiling water required to dissolve 0.200 g is
(100mL x 0.200g)/(1.22 g)

= 16.39 mL
