# What is the molar mass of sulfuric acid H_2SO_4?

Apr 8, 2017

#### Answer:

Sulfuric acid's molar mass is $\text{98.08 g/mol}$.

#### Explanation:

Step one: Find the atomic masses in each atom -- units: $\text{g/mol}$

• Hydrogen: $1.01$
• Sulfur: $32.06$
• Oxygen: $16$

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

• Hydrogen: $2$ atoms
• Sulfur: $1$ atom
• Oxygen: $4$ 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):

$\text{MM} = \left(1.01 \times 2\right) + 32.06 + \left(16 \times 4\right)$

$= \text{ 98.08 g/mol}$

Hope this helped!
