You will be expected to have a functioning calculator with you for every chemistry class. The only new concept we will introduce in this unit is the idea of a mole. A mole is a quantity of matter that we use for conversion purposes. We can convert from grams to moles, liters to moles (for gases), and atoms, formula units, or molecules to moles.
