A flexible container has a volume of 22.5 liters when there is 1.00 moles of gas in it at STP. Determine the number of miles of gas that must be contained if the volume is increased to 30.0 liters.

1.33moles

Explanation:

N1 = 1.0 moles

V1 = 22.5L

V2 = 30L

N2 = ?

From mole - volume relationship,

N1 / V1 = N2 / V2

N2 = (N1 * V2) / V1

N2 = (1.0 * 30) / 22.5

N2 = 1.33moles

Number of moles of the gas is 1.33 moles
