Question

molecular mass of magnesium chloride

Answer 1

First you look up molar masses in a data book, periodic table, etc.

Write down the molar mass of each element. In this case:

Magnesium: 24.305 grams per mole

Chlorine: 35.45 grams per mole

Then write the chemical formula of magnesium chloride down. I assume you know how to determine chemical formulas of simple compounds.

MgCl2

To determine the molar mass multiply the molar mass of each element in the compound by the number of atoms of each element in the compound.

(24.305gmol^-1 x 1) + (35.45gmol^-1 x 2)

= 95.205 grams per mole.

Answer 2

hey dude .
ur amswer is here.......!!!!

molecular mass of magnesium chloride is 95.205 gram per mole.

Magnesium:
24.305 grams/mole

Chlorine:
35.45 grams/mole

Then write the chemical formula of magnesium chloride down.
MgCl2

now multiply the given elements with there molar mass and atomic no.

(24.305gmol^-1 x 1) + (35.45gmol^-1 x 2)

= 95.205 grams per mole.

thanks.....!!!!
