Answer:
2.38×10⁻²² g
Step-by-step explanation:
Molar mass is defined as the mass of 1 mole of the substance.
Since the molar mass fo AgCl is 143.32 g/mol
Since, 1 mole of AgCl contains 6.022×10²³ molecules of AgCl
So,
6.022×10²³ molecules of AgCl has a mass of 143.32 g
Also,
1 molecule of AgCl has a mass of 143.32/6.022×10²³ g
Mass of 1 formula unit of AgCl is 2.38×10⁻²² g
