Answer:

The percent composition of CuO is 80%(Cu) and 20%(O)

Explanation:

Given:

Percent (%) Composition of CuO

Cu = 1 x 50g      - Multiply by one as there is one Cu

O = 1 x 12.5g      - Multiply by one as there is one O

CuO = 62.5g

% for Cu = 50g over 62.5 multiplied by 100 = 80%

% for O = 12.5g over 62.5 multiplied by 100 = 20%

Final Answer :

Percent (%) Composition of CuO = 80% (Cu) & 20% (O)
