What is the mass in grams of one mole of MgCl2?
95.21 grams To find a molar mass, we have to go to our periodic table and add up the grams in the table for 1 mole. MgCl2 has two Cl's and 1 Mg in it. So we need to add up 2 times 35.45 and then plus 1 Mg, which is 24.31. And we end up with 95.21 grams for 1 mole.
