Calculate the mass of agcl that should be produced when an excess of agno3 is reacted with 500 mg

Answer is: mass of silver chloride is 0.573 grams.

Balanced chemical reaction:

2AgNO₃ + [Co (NH₃) ₅Cl]Cl₂ → 2AgCl + [Co (NH₃) ₅Cl] (NO₃) ₂.

m (Co (NH₃) ₅Cl]Cl₂) = 500 mg : 1000 mg/g = 0.5 g.

n (Co (NH₃) ₅Cl]Cl₂) = 0.5 g : 250.4 g/mol.

n (Co (NH₃) ₅Cl]Cl₂) = 0.002 mol.

From chemical reaction: n (Co (NH₃) ₅Cl]Cl₂) : n (AgCl) = 1 : 2.

n (AgCl) = 2 · 0.002 mol = 0.004 mol.

m (AgCl) = 0.004 mol · 143.32 g/mol.

m (AgCl) = 0.573 g.
