The unit "g mol" typically refers to grams per mole, which is a unit used to express the molar mass of a substance. It indicates the mass of one mole of a given substance in grams. For example, if a compound has a molar mass of 58.44 g/mol, it means that one mole of that substance weighs 58.44 grams. This unit is crucial in chemistry for converting between the mass of a substance and the amount in moles.

How many formula units make up 40.0 g of magnesium chloride (MgCl2)?
To find the number of formula units in 40.0 g of magnesium chloride (MgCl2), first calculate its molar mass. The molar mass of MgCl2 is approximately 95.21 g/mol (24.31 g/mol for Mg and 35.45 g/mol for Cl, multiplied by 2). Next, divide the mass of the sample by the molar mass: 40.0 g ÷ 95.21 g/mol ≈ 0.420 mol. Finally, multiply the number of moles by Avogadro's number (6.022 x 10²³ formula units/mol) to get approximately 2.53 x 10²³ formula units of MgCl2.
