What is the mass of 5.50 moles of magnesium chloride, MgCl2?

522.5g

Explanation:

First, we'll begin by calculating the molar mass of MgCl2.

This is illustrated below:

Molar Mass of MgCl2 = 24 + (2x35.5) = 24 + 71 = 95g/mol

Mole of MgCl2 obtained from the question = 5.50 moles

Mass of MgCl2 =?

Mass = number of mole x molar Mass

Mass of MgCl2 = 5.50 x 95

Mass of MgCl2 = 522.5g

Therefore, the mass of 5.50 moles of magnesium chloride, MgCl2 is 522.5g
