What is the molar mass of magnesium carbonate, MgCO3? 52.314 g/mol 84.313 g/mol 96.771 g/mol 102.588 g/mol

Molar mass of MgCO3 = 84.3 g/mol

Explanation:

What is the molar mass of magnesium carbonate.

Molar mass of a substance is defined as the mass of one mole of the substance expressed in grams hence its unit is gram per mole (g/mol)

MgCO3 is a compound and it's molar mass would be the sum of the molar masses of the elements that make up the compound. MgCO3 contains 1 atom of magnesium, one atom of carbon and 3 atoms of oxygen

Molar mass of Magnesium = 24.3g

Molar mass of Carbon = 12g

Molar mass of Oxygen = 16g

Molar mass of MgCO3 will be

24.3 + 12 + 16*3

= 24.3 + 12 + 48 = 84.3 g/mol

Molar mass of MgCO3 = 84.3 g/mol
