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)
