Question

Calculate the mass % of copper, and also of zinc. Show your calculation work.

Answer 1

Answer:

Explanation:

dpenny = (% )dCu + (% )dZn

dpenny = ()dCu + ()dZn

Where:

% + % = 100

= 1.00 −

dpenny = ()dCu + (1.00 − )dZn

dpenny = ()dCu − ()dZn + 1.00

dpenny = ()[ − ] + 1.00

=

− 1.00

−

= % �
