    x = 4.5

    4.5 moles of C2H6 is required to produce 13.5 moles of H2O

    Explanation:

    Given equation is:

    2 C2H6 + 7 O2 → 4 CO2 + 6 H2O

    if it requires 2 moles of C2H6 to produce 6 moles of H2O

    then x moles of C2H6 is required to produce 13.5 moles of H2O

    Using unitary method for solving, we get

    x = 13.5 x 2 / 6

    x = 13.5 / 3

    x = 4.5

    Therefore, 4.5 moles of C2H6 is required to produce 13.5 moles of H2O
