Answer:
95.2 g/mol
Step-by-step explanation:
To calculate the molar mass of MgCl2
We have to separately see the molar masses of Magnesium and Chlorine
Molar mass of Magnesium: 24.305 g/mol
Molar mass of Chlorine: 35.453 g/mol
As there are two atoms of chlorine in the said molecule so the molar mass of chlorine will be multiplied by 2.
35.453*2 = 70.906 g/mol
So the total molar mass of the said molecule = Molar mass of Mg + Molar mass of two atoms of chlorine
= 24.305 + 70.906
=95.211 g/mol
Rounding off to .1
95.2 g/mol
