National Mole Day is today. Please choose from the following the type of mole that is being recognized:
1) the kind that lives in the ground
2) the kind that lives on your skin
3) the kind who infiltrates an organization
4) a spicy sauce made with chilies and usually chocolate
5) a mass (in grams) whose number is equal to the atomic mass of the molecule
If you said #5 you would probably fall down laughing at this joke that passes for humor in chemistry circles:
