Tablets taken by patients suffering from anaemia contain 0.2g of iron sulfate (FeSO4). Calculate the relative formula mass of iron sulfate. Give your answer to the nearest whole number.

152g

Explanation:

The compound given here is iron sulfate and it is represented as;

               FeSO₄

The relative formula mass of the compound is determine by the addition of its component atomic masses and them expressed in grams

Atomic mass of Fe = 55.845

                           S = 32.065

                           O = 15.994

So;

Relative formula mass  = 55.845 + 32.065 + 4(15.994)  = 151.886g

Therefore, solution is 152g
