    Answer:

    0.312 moles of H2O

    Explanation:

    no. of moles of ch4= mass ÷ molar mass

                                   =2.5 ÷ 16.04

                                   =0.156 moles of ch4

    According to balanced chemical equation

    CH4        :        H2O

    1 mole     :        2 moles

    0.156 moles :       x moles  

    by cross multiplication

    x=  (0.156×2) ÷ 1

     = 0.312 moles of H2O
