Determine the temperature of 1.42 mol of a gas contained in a 3.00-L container at a pressure of 123 kPa

The temperature is 30,92K

Explanation:

We use the formula PV=nRT. We convert the unit of pressure in kPa into atm.

101,325kPa1atm

121kPax=(121,3kPax 1 atm)/101,325kPa=1, 2 atm

PV=nRT>T= (PV)/(RT)

T=(1,2 atm x 3L)/(1,42 mol x 0,082 l atm/K mol )= 30, 91721058 K
