Answer:

Hey,

QUESTION)

A) Let's first calculate the molar mass M of the molecule :

M(Ca(OH)₂) = M(Ca) + 2M(O) + 2M(H)

  • M(Ca(OH)₂) = 40 + 2 x 16 + 2 x 1
  • M(Ca(OH)₂) = 74 g/mol

B) Let's deduct the corresponding mass m :

m = M x n

  • m = 74 x 0.456
  • m = 33.744 g
  • m ≈ 34,0 g

The mass of calcium hydroxide corresponding to this quantity of substance (in mol) is therefore 34 g.
