Calculate the molecular (formula) mass of the compound: iron(II) acetate tetrahydrate. A. 186.9 amu B. 245.9 amu C. 191.5 amu D. 242.7 amu E. 197.9 amu

The correct answer is option B.

Explanation:

The molecular formula of iron(II) acetate tetrahydrate.;

Atomic mass of iron = 55.84  amu

Atomic mass of carbon = 12.01 g/mol

Atomic mass of oxygen = 16.00 amu

Atomic mass of hydrogen = 1.01 amu

Molecular mass of  iron(II) acetate tetrahydrate:

The closest option to 246.02 amu is 245.9 amu.

So, the correct answer is option B.
