    The answer to your question is: 98 gr / mole

    Explanation:

    Molecular weight and molecular mass are synonyms and they referred to sum of the the molecular masses of the elements that form part of a compound. Their units are grams / mole

    In your example we need to sum the molecular mass of the components of sulphuric acid.

    Like this:

    Hydrogen (H) = 1.008 x 2

    Sulphur (S) = 32 x 1 = 32

    Oxygen = 16 x 4 = 64

    Total = 98 gr / mole
