Question

What is the minimum mass of water that would be needed to dissolves 45 g of Z at 62 degree celcius.

Answer 1

Solubility =$\frac{mass \space of \space compound}{mass \space of solvent(water)}\times 100g$

So, when given solubility, minimum mass of water required in this case $=\frac{45}{solubility}\times 100g$
