Question

When sodiuni chloride reacts with silver ni-

trate, silver chloride precipitates. What mass
of AgCl is produced from 195 g of AgNO3?
Answer in units of g.
pre

Answer 1

164.82 g

Step-by-step explanation:

Given data:

Mass of AgNO₃ = 195 g

Mass of AgCl = ?

Solution:

Chemical equation:

NaCl + AgNO₃ → AgCl + NaNO₃

Number of moles of AgNO₃:

Number of moles = mass/molar mass

Number of moles = 195 g / 169.87 g/mol

Number of moles =1.15 mol

Now we will compare the moles of AgNO₃ with AgCl.

AgNO₃ : AgCl

1 : 1

1.15 : 1.15

Mass of AgCl:

Mass = number of moles × molar mass

Mass = 1.15 mol × 143.32 g/mol

Mass = 164.82 g
