Question

Calculate the molar mass of Iron (II) chloride (3 sig figst

Answer 1

Answer:

127g/mol

Explanation:

First, let us write the formula of Iron (II) chloride. This is illustrated below:

From name of the compound, we discovered that iron has oxidation number of 2.

Therefore, Iron (II) chloride is written as FeCl2

Now, we can obtain the molar mass of FeCl2 as follow:

Molar Mass of FeCl2 = 56 + (35.5 x 2) = 56 + 71 = 127g/mol

Answer 2

126.751 g/mol

Formula: FeCl2
