Answer:
Mass = 32.69 g
Explanation:
Given data:
Mass of copper = 32 g
Mass of zinc formed = ?
Solution:
Chemical equation:
Cu + Zn(NO₃)₂ → Cu(NO₃)₂ + Zn
Number of moles of copper:
Number of moles = mass/molar mass
Number of moles = 32 g/ 63.55 g/mol
Number of moles = 0.5 mol
now we will compare the moles of zinc with copper.
Cu : Zn
1 : 1
0.5 : 0.5
Mass of Zn:
Mass = number of moles × molar mass
Mass = 0.5 mol × 65.38 g/mol
Mass = 32.69 g
Heat the sulfuric acid solution and adding copper carbonate in it.
<h3>Improvement require in this experiment</h3>
The method could be improved by heating sulfuric acid solution and add copper carbonate into the solution of sulfuric acid. Add the copper carbonate until it is present in excess amount. After that filter the extra amount of copper carbonate so in this way the blue copper sulfate crystals are produced.

Answer:
It represents the <em>number of atoms</em> of that particular element present in the compound. In C₂H₄O₂ there are 2 Carbon atoms, 4 Hydrogen atoms and 2 Oxygen atoms.
