What is the formula mass of calcium acetate?

Answer 1

Calcium acetate, or Calcium ethanoate, has the molecular formula

(CH3COO)2Ca.

The atomic weights of Carbon, Hydrogen, Oxygen and Calcium are 12, 1, 16 and 40, respectively.

So, the formula mass is 2 x ((1 x 12) + (3 x 1) + (2 x 16)) + (1 x 40) = 134

Answer 2

The formula for calcium acetate is Ca(C2H3O2)2. To calculate the formula mass, we add up the atomic masses of all the elements in the formula: Ca (40.08 g/mol) + 2(C) (24.02 g/mol) + 3(H) (3.03 g/mol) + 2(O) (16.00 g/mol). This gives us a formula mass of 158.15 g/mol.
