Question

What is the molar mass of sulfuric acid `H_2SO_4`?

Answer 1

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

Explanation:

Step one: Find the atomic masses in each atom -- units: `"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):

`"MM" = (1.01xx2) + 32.06 + (16xx4)`

`= " 98.08 g/mol"`

Hope this helped!
