I think you are missing a piece of information. What is the mass of each clock brass.
Q. Clock brass consists of 64.25% copper, 34% zinc and 1.75% lead. A manufacturer has an unlimited supply of copper and lead but has only 50kg of zinc. How much closs brass can he make?
Simple problem but I just can't get the answer.
Please show your working out and don't just give the answer.
