0ne mole of CuSO4.5H2O contains 6.023×10^23 no.of molecules
Again, 1 mole CuSO4.5H2O contains 9 oxygen atoms
Therefore,1 mole CuSO4.5H2O contains 9 × 6.023×10^23 no.of oxygen atoms
Hope this help!

Answer:

Explanation:
<u>Definition of weight:</u>
- The gravitational force acting on a body is called weight.
<u>Explanation:</u>
The weight of the body changes with different factors concerned e.g. height h, acceleration due to gravity g etc.
We know that,
W = mg
Mass is a constant quantity, however g changes with the altitude or place. Consequently, weight also does not remain constant.
<u>Example:</u>
An object having mass 1 kg will have a weight of 9.8 N on Earth while its weight on moon will be 1.6 N due to the difference in the values of g.
