Web18.016 amu is the mass of a single water molecule. 15. If the formula mass of iron(II) sulfate (FeSO 4) is 151.9 amu, what is the molar mass of iron(II) sulfate. ... mass units (amu) and grams (g) is 1 gram = 6.022 x 1023 amu. Quick Check - copy the question and all the responses, WebApr 6, 2024 · Atomic weight of oxygen = 16 amu. Molecular weight of water= 2 (weight of hydrogen atom) + weight of oxygen atom. M H 2 O = 2 M H + M O. M H 2 O = 2 × 1 + 16. M H 2 O = 2 + 16. M H 2 O = 18 a m u. So the molecular weight of water will be 18amu. So, the correct answer is “Option B”.
