Question

The pressure exerted by a gas is 2.5 atm while it has a volume of 150 cm³. What would be the volume of this sample of gas at standard atmospheric pressure?

Answer:

The combined gas law is:

$$\frac {P V}{T} = \frac {P _ {1} V _ {1}}{T _ {1}}$$

Assume the temperature is constant in this case, as it isn't mentioned in the task. Therefore:

$$P V = P _ {1} V _ {1}$$

$P_{1}$ – standard atmospheric pressure, $P_{1} = 1$ atm.

The volume of this sample of the gas at standard atmospheric pressure would be:

$$V _ {1} = \frac {P V}{1} = \frac {2.5 \cdot 150}{1} = 375 \text{ cm}^3$$

Answer: $375 \text{ cm}^3$
