Question

Molecular mass of MgCl2​ with calculation

Answer 1

Answer:

Using a periodic table, one would fine that:

Molar mass (M) of Magnesium (Mg) = 24.31 g/mol

Molar mass (M) of Chlorine (Cl) = 35.45 g/mol, since we have two chorine atoms in this particular molecule, we simply multiply the molar mass of 1 Cl atom by 2 so that we have 70.90 g/mol of Cl.

Hence molar mass (M) of Magnesium Chloride; MgCl.= M (2Cl)+M (Mg) = 70.90+24.31=95.21 g/mol
