Lab 5AL Mole Baggie Lab

In this lab, we needed to determine mystery substances in plastic bags using given measurements of the substance. We began by weighing the filled bag on the scale to find the total mass, and then we also used our given total mass to find the mass of our substance. For Set A, we calculated the molar mass by dividing the mass of the substance by the given number of moles. For Set B, we first converted the given number of respective particles to moles, and then we calculated the molar mass using the same given formula. Next we compared our calculated molar masses to the molar masses of the possible compounds. Our results were A4 is Calcium Carbonate and B3 is Potassium Sulfate.
