Oxygen and cyclopropane at partial press...

Oxygen and cyclopropane at partial pressures orf 570 torr and 170 torr respectively are mixed in a gas cylinder. What is the ratio of the number of moles of cyclopropane to the number of moles of oxygen?

A

`(170)/(740)=0.23`

B

`((170)/(742))/([(170)/(42)+(570)/(32)])=0.19`

C

`(170+42)/(570+32)=0.39`

D

`(170)/(570)=0.30`
