chemistry hw Calculate the volume of a N2 having a pressure of 2.33atm, temperature of 43oC and a mass of 34g.

Question

Calculate the volume of a N2 having a pressure of 2.33atm, temperature of 43oC and a mass of 34g.

Answer 1

Ideal gas law:

PV = nRT

You have the P (pressure) of 2.33 atm

You have the temperature of 43ºC but you MUST convert it to K by adding 273

R is a constant of 0.0821 Latm/Kmol

n is the number of moles which isn't given to you directly, but you can calculate it from the mass of 34 g N2. (you simply divide 34 g by the molar mass of N2 which is 28 g/mol)

And you then can solve for V (volume)...

V = nRT/P Just plug in the values from above and solve. Your answer will be in units of liters.
