Final answer:
The mass of 4 x 6.022 x 10^23 oxygen atoms is 64 grams.
Step-by-step explanation:
The mass of 4 x 6.022 x 10^23 oxygen atoms can be calculated using the molar mass of oxygen. The molar mass of oxygen is approximately 16 grams per mole. Since there are 6.022 x 10^23 atoms in one mole, we can calculate the mass of 4 x 6.022 x 10^23 oxygen atoms as follows:
(4 x 6.022 x 10^23) / (6.022 x 10^23) x 16 grams/mol = 64 grams
