Calculate the % of each element in calcium carbonate. (Atomic mass: C-12, O-16, Ca-40)

Text Solution

Verified by Experts

Molar mass of `CaCO_3 =40 +12+(3xx16)`
= 100
% of an element
`=( "Mass of an element in the compound ")/(" Molar mass of compound ")xx100`
% of C in `CaCO_3 =(12)/(100)xx100 =12% `
% of O in `CaCO_(3) =(16xx3)/(100)xx100= 48 % `
% of Ca in `CaCO_(3) =(40 )/(100)xx100 = 40 % `
