Post 4 Gas Laws

We did the airbag lab today that involved mixing baking soda and vinegar (5%) to produce CO2 in a bag. Starting this lab we found the volume of the bag by filling it with water before converting this amount (mL converted to L) into mols using the equation PV=nRT. After getting the mols, we used this number to find the grams of baking soda needed (stoichiometry) and the mL of vinegar needed (mols of vinegar x 20/1.05 [density]). After that, the lab was smooth sailing.
