# Chemistry: Particles <==> Moles <==> Grams

We have 14 ready-to-use problem sets on the topic of Particles, Moles, and Grams. These problem sets focus on the use of Avogadro's number and molar mass values to convert between the number of particles in a sample, the moles in a sample, and the mass of the sample. Percent composition calculations, empirical formula determinations, and average atomic mass calculations are also included in this set of problems.
