    96g

    Explanation:

    To know the exact mass of carbon (C) to add to the reaction, we need to convert 8 moles of carbon (C) to grams.

    This is illustrated below:

    Molar mass of C = 12g/mol

    Number of mole of C = 8 moles

    Mass of C = ... ?

    Mass = number of mole x molar mass

    Mass of C = 8 x 12

    Mass of C = 96g

    Therefore, 96g of carbon (C) is needed.
