    A. 0.0440 moles/day

    Explanation:

    First, let's figure out how many moles 33.23 grams of silver is. We do this by dividing the number of grams by the molar mass of silver, which is 107.87 g/mol:

    33.23 g Ag : 107.87 g/mol = 0.3081 mol Ag

    Now, let's divide this by 7 to get the rate per day:

    0.3081 mol Ag : 7 days = 0.0440 mol/day

    Thus, the answer is A.
