2. An 18.0 liter container holds 1.20 moles of oxygen gas at 45.0 degrees Celsius. What is the
pressure in the container? *

Respuesta :

Answer:

The pressure in the container is 1,7 atm.

Explanation:

We convert the unit of temperature in Celsius into Kelvin:

0°C= 273K --> 45°C= 45 + 273= 318 K

We use the formula:

PV=nRT ---> P =nRT/V

P= 1,20 mol x 0,082 l atm/K mol x 318 K/18,0 L

P= 1, 7384 atm
