Answer:
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.:)
