A gas occupies 300ml at 27^(@)C and 730 mm pressure. What would be its volume at STP -

Answer»

162.2 ml
262.2 ml
362.2ml
462.2ml

Solution :Given at `T_(1) = 300 K,T_(2) = 273 K` (STP )
`4V_(1) = 300 ml = (( 300)/( 1000) ) `LITRE , `P_(1) =((730)/( 760))` ATM. `P_(2) = 1` atm, `V_(2)=?`
`(P_(1)V_(1))/( T_(1))=(P_(2)V_(2))/( T_(2))`,
`( 730 xx 300)/( 760 xx 1000 xx 300 ) =( 1 xx V_(2))/( 273) `
`:. V_(2) = 0.2622 `litre =262.2 ml
