    Answer: 26 moles of PH_3 are required for the reaction.

    Explanation:

    We are given:

    Moles of P_4O_{10} = 6.5 moles

    The given chemical reaction follows:

    4PH_3(g)+8O_2(g)\rightarrow P_4O_{10}(s)+6H_2O(g)

    By the stoichiometry of the reaction:

    If 1 mole of P_4O_{10} is produced by 4 moles of PH_3

    So, 6.5 moles of P_4O_{10} will be produced by = \frac{4}{1}\times 6.5=26mol of PH_3

    Hence, 26 moles of PH_3 are required for the reaction.
