Mole Conversions

A mole represents 6.022×10²³ atoms.An element's atomic mass is the mass of a single atom of that element. The molar mass, therefore, is calculated by multiplying the atomic mass by the number of moles of that element.

A mole represents 6.022×10^23 atoms. An element’s atomic mass is the mass of a single atom of that element. This Formula Solver! Series program will walk you through the steps for using atomic mass, moles, and molar mass to convert between moles and grams.

Once your determine the molar mass of a compound, you are prepared to do the mole conversions.

When given the sample size of the compound in moles, the mass in grams of the sample is described as g = Mn where g is the total grams of the sample, M is the molar mass of the compound, and n is the sample size in moles.

Conversely, when given the total grams of the sample, the size in moles of the sample is described as n = g/M where n is the sample size in moles, g is the sample mass in grams, and M is the molar mass of the compound.
