The total pressure of a sample of methane collected over water is 735 torr at `29^(@)C` .The aqeous tension at `29^(@)C` is 30 torr. What is the pressure exerted by dry methane -

605 torr

205 torr

405 torr

705 torr

Text Solution

Verified by Experts

The correct Answer is:

`P_("total") = P_("dry methane ") + P_("water")`
`735 = P_("dry methane ") +30`
`:. P_("dry methane ") = 735 - 30 =705 ` torr .
