First step: The mass of zinc in the yellow zinc sample can be calculated with the help of percentage (given) in the sample. After that, mass of copper is determine by the subtracting the mass of zinc from the total mass of zinc in the given sample.
Thus,
Mass of zinc in 34% zinc sample =
= zinc
Mass of zinc in 37% zinc sample =
= zinc
Now,
mass of copper in 34% zinc sample =
=
mass of copper in 37% zinc sample =
=
Thus, the range of mass of copper is to
Second step:
34% zinc sample consist of 66% copper (100-34= 66%)
37% zinc sample consist of 63% copper (100-37=63%)
Mass of zinc =
=
Mass of zinc =
=
Thus, the range of mass of zinc is to
