If i have a 50 L container that holds 45 moles of gas at a temperature of 473 K, what is the pressure inside the container?
Furkat [3]

Answer:

The pressure inside the container is 34.97 atm

Explanation:

Given:

V=50L R= 0.0821LatmK^-1mol^-1

n= 45mol T= 473k

PV=nRT

P= nRT/V

= 45mol*0.0821Latmmol^-1K^-1*473K/ 50L

=34.95atm
