# Problem: A 15-L cylinder contains 4.0 g of hydrogen and 28 g of nitrogen. If the temperature is 27oC what is the total pressure of the mixture?

###### FREE Expert Solution

Recall that the partial pressure of a gas (PGas) in a mixture is given by:

$\overline{){{\mathbf{P}}}_{{\mathbf{gas}}}{\mathbf{=}}{{\mathbf{\chi }}}_{{\mathbf{gas}}}{{\mathbf{P}}}_{{\mathbf{total}}}}$

where:

χGas = mole fraction of the gas

Ptotal = total pressure of the gas mixture
