How is the molar mass of magnesium chloride calculated?

Best Answers

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. read more

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. read more

If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. read more

It will calculate the total mass along with the elemental composition and mass of each element in the compound. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. You can use parenthesis or brackets []. Finding Molar Mass.
