Answer 2

Given:

Copper oxide molecule consists of Cu and O atoms.

To find:

Weight ratio of Cu and O.

Solution:

CuO consists of Cu atom and O atom.

CuO → Cu + O

that means 1 mole of Cu and 1 mole O is combines to form copper oxide which weight will be equivalent to atomic weight.

Atomic mass of Cu = 63.546u

Atomic mass of O = 16u

so, required weight of Cu = 63.546u

and required weight of O = 16u

So, in CuO, expected weight proportion is,

$\frac{ Cu}{O} = \frac{63.546}{16}$

$\frac{ Cu}{O} = \frac{3.971}{1}$

Cu:O = 3.971 : 1

Hence, the weight ratio is found to be 3.971 : 1.
