Sulfuric acid's molar mass is $98.08 g/mol$ $"98.08 g/mol"$ .

Explanation:

Step one: Find the atomic masses in each atom -- units: $g/mol$ $"g/mol"$

Hydrogen: $1.01$ $1.01$

Sulfur: $32.06$ $32.06$

Oxygen: $16$ $16$

Step two: Find how many of those atoms are of the formula:

Hydrogen: $2$ $2$ atoms

Sulfur: $1$ $1$ atom

Oxygen: $4$ $4$ atoms

Step three: Add all the atomic masses together. (Note, if there are more than one of a particular atom, you must multiply it by how many of that atom is in that formula):

$MM = (1.01 \times 2) + 32.06 + (16 \times 4)$ $"MM" = (1.01xx2) + 32.06 + (16xx4)$

$= 98.08 g/mol$ $= " 98.08 g/mol"$
