Question 55

A solution of lithium hydroxide had a concentration of 0.150 mol dm-3.

This lithium hydroxide solution was prepared by dissolving 1.80 g of an impure commercial sample of lithium hydroxide to form 400 cm3 of solution.

Calculate the percentage by mass of lithium hydroxide in the impure sample.

(relative formula mass: LiOH=24.0\text{LiOH} = 24.0LiOH=24.0)
