Determine the mass fraction of zinc in zinc sulfate.

Zinc sulfate has the chemical formula ZnSO4.

It consists of 1 zinc atom, 1 sulfur atom and 4 oxygen atoms.

In order to calculate the mass fraction of zinc in zinc sulfate, it is necessary to find the ratio of the molar mass of zinc to the molar mass of the zinc sulfate molecule.

M Zn = 65 grams / mol;

M ZnSO4 = 65 + 32 + 16 x 4 = 161 grams / mol;

K Zn = 65/161 = 0.4037 = 40.37%;
