One litre of O(2) and one litre of h(2) ...

One litre of `O_(2)` and one litre of `h_(2)` are taken in a vessel of 2 litre capacity at `NTP` The gases are made to combine to form water .
The weight of water formed .

A

`7.03 xx 10^(-1) g`

B

`8.03 xx 10^(-2) g`

C

`8.03 xx 10^(-1) g`

D

`7.03 xx 10^(-2) g`

Text Solution

Verified by Experts

At `NTP` the moles of `H_(2)O` formed =mole of `H_(2)`
`=(PV)/(RT)=(1xx1)/(0.0821 xx273) =4.46 xx 10^(-2)`
`:.` wt of `H_(2)O` formed ` =4.46 xx 10^(-2) xx18`
` = 8.03 xx 10^(-1) g` .
