Answer:
% age Composition of Calcium = 36 %
% age Composition of Chlorine = 64 %
Explanation:
Percent composition can be defined as the relative amounts of each element in a compound. It is calculated as,
% age Composition = Mass of element / Mass of compound × 100
Given Data:
Mass of Calcium = 0.90 g
Mass of Chlorine = 1.60 g
Mass of Compound = 2.50 g
Calculating %age composition of Calcium:
% age Composition = Mass of Calcium / Mass of compound × 100
% age Composition = 0.90 g / 2.50 g × 100
% age Composition = 36 %
Calculating %age composition of Chlorine:
% age Composition = Mass of Chlorine / Mass of compound × 100
% age Composition = 1.60 g / 2.50 g × 100
% age Composition = 64 %
