Here the concept of Molarity used .We will put the formula of Molarity then we find moles of copper sulphate .Then we can find the.Given weight of Copper sulphate.So let's do
<h3>
Solution:-</h3>
- Volume of Solvent=0.8L
- Molarity=0.6M
We know




Now
Molar Mass of Solute:-






Now




Carbon atoms oxidation number is +2.Hydrogen's oxidation number is +1.Oxygen's oxidation number is -2.
