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
`P_("Total") = P_(A) + P_(B)`
`= (500 xx 1000)/(2000) + (1000 xx 800)/(2000)`
`= 250 + 400 = 650` torr
