A sample of 5.00 mol of gas in a 10.00 L container is at 45.0 °C. What is the pressure of the gas?
katrin2010 [14]

Answer:

The pressure of the gas is 13, 04 atm.

Explanation:

We use deal gas formula. First, we convert the unit of temperature in Celsius into Kelvin. We use the constant R= 0,082 l atm /K mol.Then, we solve P (pressure).

0°C=273 K   45°C= 273 + 45= 318 K

PV=nRT   -----> P= (nRT)/V

P= (5 mol x 0,082 l atm /K mol x 318 K)/ 10 L

<em>P= 13,038 atm</em>
