Question

Calculate the relative molecular mas of Calcium Chloride

Answer 1

Answer:
110.98 g.

Explanation:
The molar mass of a compound is just the molar masses of every element in the compound added up. Since the molar mass of Calcium is 40.08 g and the molar mass of Chlorine is 35.45, it would be
40.08
g

35.45

(with 2 Chlorines according to the subscript.) That leaves you with 110.98 g.

Answer 2

Formula pf Calcium chloride

The formula of calcium chloride is given by CaCl₂ .

Mass of each atom

Ca = 40

Cl = 35.5

Now we can easily calculate the mass .

Molecular mass = ( 40 + 35.5 × 2 ) g

                          = ( 40 + 71 ) g

                          = 111 g

The mass is 111 g .
