If 500 mL of gas A at 1000 torr and 1000 mL of gas B at 800 torr are placed in a 2 L container, the final pressure will be

A

100 torr

B

650 torr

C

1800 torr

D

2400 torr

Text Solution

Verified by Experts

The correct Answer is:
B
`n_(A)=(1000 xx 500)/(RT), n_(B)=(1000 xx 800)/(RT), n_(T)=n_(A)+n_(B)= (1300 xx 1000)/(RT), P_("final")= ((1300 xx1000)/(RT) xxRT)/(2000)=650`
