If the standard molar enthalpy change for combustion of graphite powder is $-$2.48 $\times$ 102 kJ mol$-$1, the amount of heat generated on combustion of 1 g of graphite powder is ___________ kJ. (Nearest integer)
Answer (integer)
21
Solution
1 mol graphite = 12 gm C<br><br>For 1 g of graphite = ${{248} \over {12}}$ = 20.67 kJ/gm heat evolved.
