Question

What pressure is exerted by a mass of `1*g` nitrogen gas that is contained in a `0.50*L` volume under standard conditions?

Answer 1

Well, the mass is easy as you have specified it.....

Explanation:

If the dinitrogen is at room temperature, `298*K`, you could also specify the pressure by means of the ideal gas equation:

`P=(nRT)/V=((7*g)/(28.02*g*mol^-1)xx0.0821*(L*atm)/(K*mol)*xx298*K)/(0.50*L)`

`~=12*atm`

Note that `1*L-=1*dm^3`, and I can use these units interchangeably.1
