# How many liters of C_3H_8 are in 1.505 xx 10^23 molecules of C_3H_8?

Apr 9, 2018

5.6 liters

#### Explanation:

There are $6.02 \cdot 1 {0}^{23}$ molecules in a mole, therefore $1.505 \cdot {10}^{23}$ molecules constitute 0.25 moles.
One mole of ideal gas at STP occupies 22.41 liters, therefore 0.25 moles of propane gas has a volume of 5.6 liters
