Answer:
= 6.7 × 10^-6 M
Explanation:
The number of moles of AgCl
= 0.0012 g/143.32 g/mol
= 8.373 × 10^-6 Moles
Concentration or Molarity = moles × volume
800 grams = 800 cm³ = 0.8 L
= 8.373 × 10^-6 Moles × 0.8 L
= 6.7 × 10^-6 M
The modern atomic model is sometimes called the electron cloud
, or quantum mechanics model.
So the answer is electron cloud
