This question really confused me. Why do you divide the solubility by the density? Could someone explain how they thought through this? Thank you in advance!!

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

A 36.0 x 10/58.5
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 1000 x 1.13/(58.5 x 136)
