Calculate the mass (in ) of each of the following.

1) 6.26*10^20 SO3
2)3.3*10^22 H2O
3)4.0*10^25 O3
4)9.98*10^19 CCl2F2

1)
(6.26*10^20 molecules SO3) / (6.022*10^23 molecules/ mole) x (80.0638 g SO3/mole) = 0.0832 g SO3

2)
(3.3*10^22 molecules H2O) / (6.022*10^23 molecules/ mole) x (18.0153 g H2O/mole) = 0.99 g H2O

3)
(4.0*10^25 molecules O3) / (6.022*10^23 molecules/ mole) x (47.9983 g O3/mole)
= 3200 g O3

4)
(9.98*10^19 molecules CCl2F2) / (6.022*10^23 molecules/ mole) x (120.9140 g CCl2F2/mole) = 0.0200 g CCl2F2
