Question

The density of 3 molal solution of naoh is 1.110 g ml^-1. Calculate the molarity of the solution

Answer 1

Answer:

2.97 M

Explanation:

You have to go by the formula,

m= 1000M/[1000d-M(Mol.wt)]

3=1000M/[1000(1.110)-M(40)]

3330-120M=1000M

3330=1120M

therefore,

M=3330/1120=2.97M

hope it helps:)
