If 1000 ml of a gas A at 600 torr and 500 ml of gas B at 800 torr are placed in a 2L flask, the final pressure will be

A

500 torr

B

1000 torr

C

850 torr

D

200 torr

Text Solution

Verified by Experts

The correct Answer is:
A
Applying Boyle.s law,
Pressure of gas A in 2L flask `= ( 1000 xx 600)/( 2000) = 300` torr
Pressure of gas B in 2L flasks `= ( 500 xx 800)/( 2000) = 200 ` torr
Total pressure `= 300 + 200 = 500 ` torr
