    Combustion of glucose takes place according to the equation,
                \[{{C}_{6}}{{H}_{12}}{{O}_{6}}+6{{O}_{2}}\to 6C{{O}_{2}}+6{{H}_{2}}O\],\[\Delta H=-72\,kcal\].
                How much energy will be required for the production of 1.6 g of glucose (Molecular mass of glucose = 180 g)    

    A) 0.064 kcal

    B) 0.64 kcal

    C) 6.4 kcal

    D) 64 kcal

    Correct Answer: B

    Solution :

    [b] \[\Delta H\,per\,1.6g=\frac{72\times 1.6}{180}=0.64\,kcal\].
