Answer:
6633 grams of M are dissolved in 9L
Explanation:
If the compound M has a solubility in acetone of 0.737 g/mL, means that in 1 mLof solution, 0.737 grams of solute is dissolved.
Let's make a rule of three:
9 L = 9000 mL
In 1 mL ___ 0.737 g of M is dissolved
In 9000 mL ___ (9000 . 0.737) /1 = 6633 grams
