50POINTS!

If I held a 45.3 moles of a gas at a constant volume of 56.4L and a temperature 310.5k, what is the pressure being exerted on the gas?

A. 20.5 atm
B. 27.7 atm
C. 23.9 atm
D. 17.4 atm

Answer 1

PV=nRT

P(56.4)=45.3×0.08206×310.5

P=1154.227/56.4

=20.4650

Approximately 20.5 then A is the answer

Answer 2

A. 20.5 atm

Step-by-step explanation:

Using the formula Pv=.nRt
