Calculating molar masses p 287 H 2 O = 18g/mole ( add the numbers off the periodic table- O = 16, H = 1 ( there at two H's) ) Try H 2 SO 4 . You should bet 98.1g/mole rounding to tenths. 3. The mole p 295 a dozen = 12, a pair = 2, a ream of paper = 500 sheets, a mole = 6.02 X 10 23 Think of a mole as a “bunch” or a “pile”. A mole is not a molecule, it is a number. 6.02 X 10 23 dollars would guarantee every person on earth an income of three million dollars per second for 100 years. 6.02 X 10
