Question

What is the percentage of cu+ in cu1.8o ?

Answer 1

TOPIC :- MOLE CONCEPT

CONCEPT :- There are two types of Cu ions, they exist as Cu+ and Cu²+ . Cu1.8O is a mixture of both the ion.Also, In any compound AxBy , the ions are ${A}^{y + } and \: {B}^{ x - }$

SOLUTION

If the ions would have been Cu+ , the compound would have been Cu2O . And, if it has been CU²+ , the compound would be CuO.

Now, let there is x ℅ of Cu+ in the compound Cu1.8O.

Then,

2 × x ℅ + 1 × (100-x) ℅ = 1.8

=> 1/100 ( 2x + 100 - x ) = 1.8

=> x + 100 = 180

=> x = 80

Hence, the compound Cu1.8O, contains 80 ℅ of Cu+.
