Question

A sample of 6.00 mol of gas in a 5.00 L container is at 45.0 °C. What is the pressure of the gas?

answer in atm

Answer 1

The formula to find ideal gas is:

PV = nRT

P is the pressure of the gas, V is the volume of the container, n is the number of moles of gas, R is the ideal gas constant (0.0821 L·atm/mol·K), and T is the temperature of the gas in Kelvin.

We need to convert Celsius to Kelvin

T = 273.15 + 45.0 = 318.15 K

P = (nRT) / V

P = (6.00 mol) x (0.0821 L·atm/mol·K) x (318.15 K) / (5.00 L)

P = 150.6 atm

Therefore, the pressure of the gas is 150.6 atm.:)
