Question

0.5 moles of CO2 have a volume of 50 L and a pressure of 0.8210 atm. What must be the temperature of the gas?

Answer 1

Answer:

1000 K

Explanation:

Given data

• Moles of carbon dioxide (n): 0.5 moles

• Volume of carbon dioxide (V): 50 liters

• Pressure of carbon dioxide (P): 0.8210 atmospheres

• Temperature of carbon dioxide (T): ?

We can find the temperature of carbon dioxide using the ideal gas equation.

$P \times V = n \times R \times T\\T = \frac{P \times V}{n \times R} = \frac{0.8210atm \times 50L}{0.5mol \times \frac{0.08206atm.L}{mol.K} }=1000 K$

The temperature of the gas is 1000 K.
