    90g

    Explanation:

    The equation for the reaction is given below:

    2H2 + O2 → 2H2O

    From the equation above,

    1 mole of O2 produced 2 moles of H2O.

    Therefore, 2.5 moles of O2 will produce = 2.5 x 2 = 5 moles of H2O.

    Now let us convert 5 moles to H2O to grams to obtain the desired result. This is shown below:

    Molar Mass of H2O = (2x1) + 16 = 2 + 16 = 18g/mol

    Number of mole of H2O = 5 moles

    Mass of H2O = ?

    Mass = number of mole x molar Mass

    Mass of H2O = 5 x 18 = 90g

    Therefore, 90g of H2O are produced
