Question

Calculate the percentage composition of the elements present in magnesium carbonate.

Answer 1

Answer:

%ofMg=7.1 and % of C is=13.6 and%of O is 57.1

Explanation:

Molar mass of magnesium carbonate=84.04. Atomic mass of magnesium is 24g. Atomic mass of C is 12g. Atomic mass of 0is16 gm %of Mg=24\84×100=7.1. % of C is 12/84×100=13.6 %of O=48/84×100=57.1
