For the solution containing Zn2 + (aq), n is 2, so the MM/n ratio will be the molar mass of Zn divided by 2: MM/n = (65.39 g/mol) / 2 = 32.70 g/mol Compare this theoretical value with your experimental result. If the plating efficiency is significantly less than 1, say it is 0.55, how would the observed MM/n ratio compare to the theoretical value? MM/n will be larger than the theoretical value. MM/n will not be affected by the plating efficiency. MM/n will be less than the theoretical value. MM/n will change significantly, but it may increase or decrease for low plating efficiencies.

    MM/n will be less than the theoretical value

    Explanation:

    Given that:

    The plating efficiency is proportional to the equivalent weight of the element Zn²⁺ (aq). i. e MM/n value

    The MM/n value = (65.39 g/mol) / 2 = 32.70 g/mol

    and the experimental plating efficiency value is approximately (0.55) which is quite lower than the usual value.

    Thus; from this observation, we can conclude that MM/n will be lesser than the theoretical value.
