Problem

Two separate cylinders each contain only

\mathrm{O_2}

and

\mathrm{N_2}

at the same temperature and pressure. • Cylinder 1:

2.0\,\text{mol}\;\mathrm{O_2}

and

3.0\,\text{mol}\;\mathrm{N_2}

• Cylinder 2:

3.0\,\text{mol}\;\mathrm{O_2}

and

7.0\,\text{mol}\;\mathrm{N_2}

Which cylinder has the greater mole fraction of

\mathrm{O_2}

? Provide a brief justification.
