<h2>Answer:</h2>

<em>Hey, </em>

<h3><u>QUESTION)</u></h3>

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

<em>M(Ca(OH)₂) = M(Ca) + 2M(O) + 2M(H) </em>

  • 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 :

<em>m = M x n </em>

  • 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.

Answer:

Ca(OH)2 molecular weight. Molar mass of Ca(OH)2 = 74.09268 g/mol. This compound is also known as Calcium Hydroxide. Convert grams Ca(OH)2 to moles or moles Ca(OH)2 to grams. Molecular weight calculation: 40.078 + (15.9994 + 1.00794)*2 ››
