1. At standard temperature and pressure, one mole of H2 gas occupies 22.4 L. What volume is occupied by 3.50 moles of H2?

A. 63.0 L

B. 78.4 L

C. 88.0 L

D. 100.8 L

Answer:

The volume occupied by 3.50 moles of H2 gas is 78.4 L.

Explanation:

When one mole of H2 gas occupies 22.4 L at standard temperature and pressure, the volume occupied by 3.50 moles of H2 can be calculated through simple multiplication.

Volume occupied by 3.50 moles of H2 = 22.4 L/mole * 3.50 moles = 78.4 L
