The heat evolved on combustion of 1 gm of starch, `(C_(6)H_(10)O_(5))x`, into `CO_(2)(g) " and " H_(2)O(l)` at constant pressure, is 4.00 kcal. Standard Ethalpy of formation of  `CO_(2)(g)" and " H_(2)O(l)` are `-94.00 " and " -65.40 "kcal"//"mol"`.  The magnitude of standard enthalpy of formation of starch (in `al//gm`)is :
