I am having difficulty finding out how 40 grams of calcium produces 74 grams of calcium hydroxide.
also how 65 grams of Zinc produces 161 grams of Zinc Sulfate
or how 65 gms of Zn = 2 gms of H

start with balanced equations.
hint: you can't compare weight (or, more accurately, mass) to weight(mass) values. You can only compare mole to mole values.
