Question 12

A stock solution of potassium bromide, KBr\text{KBr}KBr, has a concentration of 47.6 g/dm3. Its relative formula mass (MrM_rMr​) is 119. A laboratory has 1.00 dm3 of this stock solution. Each batch requires 200 cm3 of potassium bromide solution at a concentration of 0.150 mol/dm3.

Calculate the number of complete batches that can be prepared from the stock solution.
