Ответ:
Ans: P = 22.5% and Cl = 77.5%
Given:
Total Mass of sample containing P and Cl = 50.51 g
Mass of P produced = 11.39 g
To determine:
Mass % of P and Cl
Explanation:
Mass % of a given element in a total mass is generally expressed as:
Mass % of element = [mass of element/total mass]*100
Here,
Total mass = mass of P + mass of Cl
mass of Cl = Total - mass of P = 50.51-11.39 = 39.12 g
% P = [11.39/50.51]*100 = 22.5%
%Cl = [39.12/50.51]*100 = 77.5%
