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

Options

A. 162.2 ml
B. 262.2 ml
C. 362.2ml
D. 462.2ml

Answer

B

Explanation

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
