Whoa, dude! you're asking what? Do you mean what number moles of zinc are dissolved in sixty seven grams of copper or brass? For the sake of argument permit's assume you meant what number moles of zinc are dissolved with sixty seven grams of copper to make brass. the quantity of brass may well be sixty seven grams of copper divided by making use of the proportion of copper, good? Multiply this by making use of the proportion of zinc and you have the quantity of zinc. Divide this by making use of the molecular weight of what?? to get the form of moles of zinc.
