Answer:
2.8212 g
Explanation:
The reaction of copper sulfate with zinc is shown below as:
Given that :
Amount of zinc = 2.9 g
Molar mass of zinc = 65.38 g/mol
The formula for the calculation of moles is shown below:
Thus, molesare:
From the reaction,
1 mole of zinc on reaction forms 1 mole of copper
Thus,
0.0444 moles of zinc on reaction forms 0.0444 mole of copper
Mass of copper = moles×Molar mass
Molar mass of copper = 63.54 g/mol
<u>Mass of copper = 0.0444 ×63.54 g = 2.8212 g</u>
