What is the pressure of 0.145 moles of nitrogen gas when it occupies 756 mL at 281.2 K?

Pressure

Pressure of 0.145 moles of nitrogen gas in a volume of 756 mL at 281.2 K is 4.22 atm.

What is pressure of gas?

Measure of the average linear momentum of the moving molecules of a gas is called the pressure of a gas.

As PV = nRT

R -- gas constant (0.08206 L·atm/mol·K).

P = nRT/V

756 mL = 0.756 L

P = nRT/V

= (0.145 mol)(0.08206 L·atm/mol·K)(281.2 K)/(0.756 L)

= 4.22 atm

Therefore, pressure of 0.145 moles of nitrogen gas in a volume of 756 mL at 281.2 K is 4.22 atm.

What is the significance of pressure of gas in this context? The pressure of gas is a measure of the average linear momentum of the moving molecules of a gas. In this context, the pressure of 0.145 moles of nitrogen gas when it occupies 756 mL at 281.2 K is calculated to be 4.22 atm by using the ideal gas law equation, P = nRT/V.
