Question 995811: Before Heating: Mass of 250 mL beaker and oil 76.552 grams
Mass of beaker + oil +20 kernels 79.691 grams
After Heating: Mass of beaker + oil + popped kernels 79.102 grams
Using the data above, calculate the initial mass of the popcorn kernels and the final mass of the popcorn kernels.

Mass of the kernels: 9.691-6.552=3.139 grams.

Mass of the loss: 9.691-9.102=0.508 grams.

Final mass of the kernels: 3.139-0.508=2.631 grams; but note that this may be ignoring any absorption of oil into the kernels.
