If the GFM of a compound is 48 grams, what is the mass of one mole of this compound?

The correct answer is: 48g

The mass of one mole of a compound is defined as its gram formula mass (GFM). The GFM represents the mass of one mole of that substance in grams. Therefore, if the GFM of a compound is given as 48 grams, this directly tells us that one mole of the compound also has a mass of 48 grams. Understanding the concept of GFM is essential in stoichiometry for mole-to-mass conversions. For example, if you are given a mass of a compound, you can use the GFM to determine how many moles you have, or vice versa, as it serves as a conversion factor based on the relationships established in the periodic table and chemical formulas. In this case, since you are provided with a GFM of 48 grams, this means that one mole of that compound weighs precisely 48 grams, making it the correct choice.
