Final answer:

The volume of 2.2 moles of nitrogen gas at standard temperature and pressure can be calculated using the ideal gas law equation. Substitute the given values and solve for V to find the volume.

Step-by-step explanation:

To find the volume of 2.2 moles of nitrogen gas at standard temperature and pressure (STP), you can use the ideal gas law equation: PV = nRT. At STP, the pressure (P) is 1 atm and the temperature (T) is 273 K. The molar mass of nitrogen gas (N₂) is 28.01 g/mol.


For this equation, you need to convert the temperature from degrees Celsius to Kelvin: 0°C + 273 = 273 K. Substitute the values into the equation:


(1 atm)V = (2.2 mol)(0.0821 L.atm/mol.K)(273 K)


Solve for V:



V = (2.2 mol)(0.0821 L.atm/mol.K)(273 K) / (1 atm)


Calculate the volume to find the answer.
