Question

A certain ionic compound X has a solubility in water of 0.773 g/mL. Calculate the greatest mass of X that could be dissolved in 500 mL of water. You may assume the volume of the solution doesn't change as the X is dissolved.

Answer 1

Answer

387 g

Procedure

We need to use a dimensional analysis considering the given solubility to solve this question. Also, we will consider 3 significant digits.

$500\text{ mL }\frac{0.773\text{ g}}{1\text{ mL}}=386.5\approx387\text{ g}$
