What is the percent composition of calcium acetate?

Answer 1

From its chemical formula, Ca(NO3)2, you can tell that there are two nitrate ions for every calcium atom. Therefore the mole ratio of calcium to nitrate is 1:2. So one could say that the "nitrate content" of calcium nitrate is 2/3 or 66.7%.

Answer 2

Calcium nitrate

Step 1: Determine the total mass of each element in the molar mass

1 mol Ca x (40.08gCa/1 mol Ca) = 40.08 g Ca

2 mol N x (14.01gN/1 mol N) = 28.02 g N

6 mol O x (16.00gO/1 mol O) = 96.00 g O

1 mol of Ca(NO3)2 = 164.1 g (molar mass)

Step 2: Calculate percent by multiplying the mass ratio by 100%

%Ca = (40.08gCa/164.1 Ca(NO3)2) x 100 = 24.42%

%N = (28.02gN/164.1 Ca(NO3)2) x 100 = 17.07%

%O = (96.00gO/164.1 Ca(NO3)2) x 100 = 58.50%

Answer 3

52.56% Barium

10.71% nitrogen

36.73% oxygen

Answer 4

The percent composition by element of Ca(C2H3O2)2 is calcium 25.339%, hydrogen 3.824%, carbon 30.375%, and oxygen 40.462%.

Answer 5

58.503%
