To determine the mass percent of Ca in Ca(CN)2 all you have to do is find the mass of Ca, divide it by the total mass of Ca(CN)2, then multiply by 100.

Therefore:

mass of Ca = 40.08 amu (or g/mol)
mass of Ca(CN)2 = 92.10 amu (or g/mol)

(40.08 amu / 92.10 amu) x 100 = 43.52% Ca in Ca(CN)2

Start with the molar mass of Ca, divide that by the total molar mass of Ca(CN)2 (Ca + Cx2 + Nx2)
