Mole Baggie Lab
In this lab, we were given two sets of bags one (A6) labeled with the number of molecules and another (B1) labeled with the number of grams. With this information, the Molar Mass was to be calculated. When the mass is calculated, there were five possible compounds that each baggie could be. There was sodium chloride, Potassium Sulfate, Zinc Oxide, Sodium Sulfate, and Calcium Carbonate.
A6 ended up with a molar mass close to Sodium Sulfate. B1 resulted in the same possible compound as A6.
To find the molar mass for A6, first the # of grams had to be found. The bag was first weighed and the weight of the bag was subtracted from the whole mass. Then the # of grams was divided by 0.045, which was the number of moles.
To find the molar mass of B1, the number of grams were given and the number of moles had to found. For this, a conversion was needed to find to find the number of moles. After that the molar mass could be found.
