Question

Find the mass of 0.456 mol of Ca(OH)2 Please if you can show the work.

Answer 1

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.

Answer 2

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 ››
