Question

What is the pressure in a 5 L tank with 1.5 moles of oxygen at 39.3 degrees Celsius?

Answer 1

Answer:

The pressure in the tank is 7, 6 atm

Explanation:

We convert the unit of temperature in Celsius into Kelvin:

0°C= 273K --> 39,3°C= 39,3+ 273= 312,3 K

We use the formula:

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

P= 1,5 mol x 0,082 l atm/K mol x 312,3 K/5 L

P= 7,68258 atm
