Unformatted text preview: ns for this lab. This experiment has three
parts. In Part A, you will time yourself counting popcorn kernels and figure out how many years it would take to
count a mole of kernels. In Part B, you will measure the mass of a dozen popcorn kernels and a dozen marbles.
You will relate these masses to the masses of individual items, and to each other. In Part C, you will measure the
volume of a mole of water molecules and the volume of a dozen marbles. Then you will calculate the volumes of
an individual molecule and a single marble. Equipment
