Solubility in moles per liter

Practice Question Solving
1

Sodium chloride (relative molecular mass = 58.5) has a solubility of 36.0 g per 100 g of water.
The density of the solution is 1.13 g/ml. Which of the following calculations would give the solubility in
moles per litre?
A) 36.0 x 1000 x 1.13/ (58.5 x 136)
B) 36.0 x 1000/(58.5 x 1.13)
C) 36.0 x 10 x 1.13/58.5
D) 36.0 x 10 x 1.13/(58.5 x 136)
E) 36.0 x 10/58.5

May I know what are the major formulae for this problem?

These are the formulae you need to use to derive the answer:

mol = mass/molar mass
density = mass / volume

make sure to convert the units!
