Question

Determine the volume (in liters) of a 87.8-9 sample of OF2 gas at 307 torr and 264°C.

Answer 1

Answer:

V = 177.4 L.

Explanation:

Hello there!

In this case, since this gas can be assumed as ideal due to the given data, we can use the following equation:

$PV=nRT\\\\PV=\frac{m}{MM}RT$

Thus, by solving for volume we obtain:

$V=\frac{mRT}{MM*P}$

So we can plug in the temperature in Kelvins (537 K), the pressure in atmospheres (0.404 atm) and the molar mass (54 g/mol) to obtain:

$V=\frac{87.8g*0.08206\frac{atm*L}{mol*K}*537K}{54g/mol*0.404atm}\\\\V=177.4L$

Best regards!
