Question

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.

Answer 1

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

Answer 2

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

Answer 3

Did your text contain :
..... the ratio of "Unexpected text node" ?
the 'unexpected text node' looks like some kind of formatting error.

Yes, the ratios are needed
