48 g of oxygen and 4 g of hydrogen are placed in 2 litre flask at `0^∘C`. Find the total pressure in atm of the gas mixture.

Options

A. 39
B. 22
C. `30`
D. None of these

Answer

A

Explanation

vol.of `CO_(2) +` vol. of remaining oxygen `= 560 ml`.
or vol. of remaining oxygen `= 112 mL`
`C_(2)H_(2)O_(x)(g) + ((5-x)/(2))O_(2)(g)overset(Delta)rarr2CO_(2)(g) + H_(2)O(l)`
`{:(224 mL,224 mL,0,-),(0,112 mL,448 mL,-):}`
for used mole of a`O_(2)`:
`((5-x)/(2)) xx 0.1 = (0.01)/(2)`
or `x = 4`
