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
