Answer:
Mass = 14.0 g
Explanation:
Given data:
Mass of mercury nitrate = 22.17 g
Mass of mercury formed = ?
Solution:
Chemical equation:
Hg(NO₃)₂ + 2K → 2KNO₃ + Hg
Number of moles of mercury nitrate:
Number of moles = mass/molar mass
Number of moles = 22.17 g / 324.6 g/mol
Number of moles = 0.07 mol
Now we will compare the moles of Hg(NO₃)₂ and mercury.
Hg(NO₃)₂ : Hg
1 : 1
0.07 : 0.07
Mass of mercury:
Mass = number of moles × molar mass
Mass = 0.07 mol × 200.6 g/mol
Mass = 14.0 g
The answer is d. The answer is that because both of them can reproduce that way.
