A metal alloy consists of copper, zinc and tin in the ratio of Unexpected text node: ’a’. The alloy is found to have 20 g of zinc.
a) What is the weight of the metal alloy?
b) calculate the weight of the other two components.

Not sure how I am supposed to figure out the weight of the metal alloy when only given the weight of zinc. Any help is appreciated, thanks.

check your typing, state the ratio in the form 4:5:7 as an example

I guess it must have been a printing error. So the question is undoable without the ratio?

the 'unexpected text node' looks like some kind of formatting error.

Yes, the ratios are needed
