The video below goes through the three basic mole problems, namely, grams-to-mole, MIAs-to-moles, and liters-to-mole. Since these are conversion factors it works in the reverse also (e.g. mole-to-grams, moles-to-MIAs, mole-to-Liters). The last problem is a two step conversion. Contact me if you would like more examples. If enough people would like additional worked problems I will put them up.
