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?
I don't understand please help.
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
