The percent composition of chlorine in the compound = 75%. That is option A
Percent composition of elements in a compound indicates the percent each element occupies in relation to the compound's total mass.
The quantity of lead in the compound= 10g
The quantity of chlorine in the compound= 30g
Therefore the total mass of the compound= 10+30= 40g
But the basic formula for % composition=
mass of element / mass of compound X 100%
%x = 30/40×100
= 3000/40
= 75%
Therefore, the percent composition of chlorine in the compound = 75%
