Answer:
The compound contains 29.3 % calcium, 23.7 % sulfur and 47 % oxygen
Explanation:
Step 1: Data given
Mass of the compound = 3.74 grams
Mass of calcium in the compound = 1.10 grams
Mass of sulfur in the compound =0.888 grams
Mass of oxygen in the compound = 1.76 grams
Step 2: Calculate percent composition
Mass of Calcium + Mass of sulfur + mass of oxygen = total mass of compound = 3.74 grams
% Caclium = (1.10 grams / 3.74 grams) * 100 % = 29.3 %
% sulfur = ( 0.888 grams /3.74 grams) *100 % = 23.7 %
% oxygen = (1.76 grams / 3.74 grams)*100 % = 47%
29.3 % + 23.7 % + 47% = 100 %
The compound contains 29.3 % calcium, 23.7 % sulfur and 47 % oxygen
