Students will ask, "What is a mole?" and you will answer some variation of, "It is 6.022 x 10^23 molecules." Then the students will ask you, "But what does that meeeaaan?"
And now you are here at this worksheet.
Use this worksheet to show them that we don't say, "Use 4 sticks of butter." We say, "Use a pound of butter." It is just an easier way to say a ridiculously large number. They will accept that. Students like easy. :)
