Gram-mole (more correctly Gram-molecule) is a synonym for Mole. See: Mole (unit) Molar mass

Use this grams to moles calculator whenever you want to know the number of moles of a substance with a specific mass.

Convert grams to moles and moles to grams using a simply calculator. Plus, learn the g to mol formula and how to account for molar mass.

The simplest type of manipulation using molar mass as a conversion factor is a mole-gram conversion (or its reverse, a gram-mole conversion). We also established that 1 mol of Al has a mass of 26.98 g (Example \(\PageIndex{1}\)).

This grams to moles/moles to grams calculator converts between moles and grams using a formula of a substance. In many chemistry problems, you need to convert grams to moles or moles to grams. The calculator below calculates the mass of the substance in grams or the quantity of the substance in moles.

Sep 7, 2024 · Grams and moles are two units that express the amount of matter in a sample. There is no "conversion formula" between the two units. Instead, you use atomic mass values and the chemical formula to do the conversion.

Need to convert between moles, molecular weight and mass? You can do it here with our mole calculator.

Jan 21, 2025 · A mole is defined as the amount of substance containing the same number of discrete entities (such as atoms, molecules, and ions) as the number of atoms in a sample of pure 12 C weighing exactly 12 g. One Latin connotation for the word “mole” is “large mass” or “bulk,” which is consistent with its use as the name for this unit.

Oct 3, 2024 · \(m\) represents the number of moles, \(M\) is the mass of the substance in grams, \(MW\) is the molecular weight of the substance in grams per mole. Example Calculation. To find the number of moles in 500 grams of water (\(H_2O\)), with a molecular weight of 18.01528 g/mol: \[ m = \frac{500}{18.01528} \approx 27.754 \]
