Question

A salt of copper and oxygen is 88.81% ( by mass) copper. Determine the empirical formula of the copper oxide salt.

check_circleAnswer
Step 1

A salt of copper and oxygen is 88.81% (by mass) copper. The empirical formula of the copper oxide salt is to be calculated.

Step 2

Determine the mass of copper and oxygen in the copper oxide-

Let the total mass of copper oxide taken = 100 g

Thus 88.81 % of this mass is copper and rest is oxygen.

Mass of Copper in copper oxide 88.81 % of 100 g
88.81
x100 88.81g
100
100 g 88.81 g = 11.19 g
Mass of oxygen in copper oxide
