Given that the solubility of potassium chlorate in water is 10.0 g/100 g water at 30 $\degree$C, what mass of potassium chlorate is dissolved in 250 grams of a saturated solution at 30 $\degree$C?
A)any mass greater than 25.0 g
B)any mass less than 10.0 g
C)any mass less than 25.0 g
D)25.0 g
E)10.0 g

Quizplus · Accepted Answer

The solubility of potassium chlorate is 10.0 g per 100 g of water. In a saturated solution, 250 g of solution contains 25.0 g of potassium chlorate (since 250 g solution = 100 g water + 10 g KClO3 + 150 g water, so 25 g KClO3 in 250 g solution).
