The heat of formation of water is `260 kJ`. How much `H_(2)O` is decomposed by `130 kJ` heat ?

A

`0.25 mol`

B

`1` mol

C

`0.5` mol

D

`2` mol

Text Solution

Verified by Experts

The correct Answer is:
C
Heat of formation of water is `260 kJ`
`:. 260 kJ` of heat decomposes `1` mole of water.
Hence `130 kJ` of heat decomposes `(1)/(260)xx130`
`=0.5` mole of water.
