antique brass is 30% zinc and 70% copper how many grams of antique brass can be made from 18 grams of zinc?

antique brass is 30% zinc and 70% copper how many grams of antique brass can be made from 18 grams of zinc and 37.8 grams of copper?

30 : 70 = 18 : x
x = 42 = mass copper needed

we have only 37.8 g copper

30 : 70 = x : 37.8
x = mass Zn needed =16.2 g

so we have 18 - 16.2 g = 1.8 g of Zn in excess

mass alloy = 16.2 + 37.8=54.0 g
