22g of CO_(2)" at "27^(@)C is mixed with 16g" of "O_(2)" at "37^(@)C. The temperature of mixture is:

Answer»

`27^(@)C`
`30.5^(@)C`
`32^(@)C`
`37^(@)C`

Solution :Here `T=(n_(1)T_(1)+n_(2)T_(2))/(n_(1)+n_(2))=((1)/(2)xx300+(1)/(2)xx310)/((1)/(2)+(1)/(2))`
`=150+155=305 K=32^(@)C`
`therefore` CORRECT choice is (a).
