The purpose of this lab is to use molar mass to identify mystery substances. We were given two baggies with two different substances, and with the mass of the empty baggies and either the number of representative particles OR the number of moles, we figured out which substances the baggies held. Since molar mass = # of grams/# of moles, we set up equations to find the number of grams per mole of each substance, and matched those with the molar masses of the given possible compounds.
