Question

A penny weighs 2.507 g and is made of an alloy which is 97.6% zinc and 2.4% copper. What is the mass of each element in the

Answer 1

Answer:

2.44 and 0.06 gram.

Explanation:

Since, from the question we get that the penny is having the weight of 2.507 gram and it is made of an alloy of zinc and copper. We know that the percentage which is present in the alloy will give us the respective mass of the compounds.

So, the mass of the zinc will be m(Zn)= 2.507g x (97.6/100) which on solving we will get that 2.446832g .

While the mass of the copper will be m(Cu)=2.507g x (2.4/100) which on solving we will get that 0.060168g.
