Moles and Grams Conversions

This video tutorial demonstrates how to convert 0.63 moles of aluminum carbonate (Al2(CO3)3) to grams. It explains the process of finding the molar mass by adding the atomic masses from the periodic table, which is 233.99 grams per mole for aluminum carbonate. The tutorial shows how to multiply the number of moles by the molar mass to get the mass in grams, resulting in 147.41 grams. It also covers the reverse process of converting grams to moles by dividing the mass by the molar mass.
