One litre N2, 7/8 litre O2 and 1 litre CO are taken in a mixture under indentical conditions of P and T. The amount of gases present in mixture is given by:

(a) ${\mathrm{\omega }}_{{\mathrm{N}}_{2}}={\mathrm{\omega }}_{{\mathrm{O}}_{2}}>{\mathrm{\omega }}_{\mathrm{CO}}$

(b) ${\mathrm{\omega }}_{{\mathrm{N}}_{2}}={\mathrm{\omega }}_{\mathrm{CO}}>{\mathrm{\omega }}_{{\mathrm{O}}_{2}}$

(c) ${\mathrm{\omega }}_{{\mathrm{N}}_{2}}={\mathrm{\omega }}_{{\mathrm{O}}_{2}}={\mathrm{\omega }}_{\mathrm{CO}}$

(d) ${\mathrm{\omega }}_{\mathrm{CO}}>{\mathrm{\omega }}_{{\mathrm{N}}_{2}}>{\mathrm{\omega }}_{{\mathrm{O}}_{2}}$
