Solution
To find the mass of 4.8 moles of oxygen molecules, we need to use the molar mass of oxygen. The molar mass of oxygen is approximately 16 grams/mole. However, an oxygen molecule (O2) consists of two oxygen atoms, so we need to double this to get the molar mass of an oxygen molecule, which is 32 grams/mole.
The calculation is as follows:
4.8 moles O2 * 32 g/mole O2 = 153.6 grams O2
So, the mass of 4.8 moles of oxygen molecules is 153.6 grams.
