Answer:
323.7g
Explanation:
Given parameters:
Number of moles of AgCl = 3 moles
Unknown:
Mass of Ag = ?
Solution:
We solve this problem by working from the known to the unknown;
The known here is AgCl;
From the balanced equation:
Zn + 2AgCl → ZnCl₂ + 2Ag
2 moles of AgCl will produce 2 moles of Ag
3 moles of AgCl will produce 3 moles of Ag
The mass of Ag will be;
Mass of Ag = number of moles x molar mass
Molar mass of Ag = 107.9g/mol
Mass of Ag = 3 x 107.9 = 323.7g
