Unformatted text preview: f the beaker and record it in Table B.
Place 12 popcorn kernels in the beaker, and determine the mass of the beaker plus popcorn. Record this mass
in Table B.
Calculate the mass of the popcorn by subtracting the mass of the beaker from the combined mass of the beaker
and popcorn. Record the result in Table B.
Use the mass of a dozen popcorn kernels to calculate the mass of a single kernel and enter this value in Table B.
Repeat steps 1 - 4 using marbles instead of popcorn kernels.

Weigh a 50 mL graduated cylinder and record its mass in Table C.
Fill the cylinder to the 18 mL mark with deionized water. Use the squeeze bottle for the last few drops. Try to
get the bottom of the meniscus (the curved surface of the water) as close to the gradation for 18 mL as you can.
Read the volume at the bottom of the meniscus and record it to the nearest 0.1 mL in Table C. It is more
important that you record the volume exac...
