How many moles of oxygen would contain 1.204 x 10^{24} molecules?
[Avogadro's constant (NA) = 6.02 x 10^{23}]

Answer Details

To determine the number of moles of oxygen, we need to use Avogadro's constant, which is the number of particles in one mole of a substance.
Given that the number of oxygen molecules is 1.204 x 10^24, we can use this information to calculate the number of moles of oxygen using the following formula:
Number of moles = Number of particles / Avogadro's constant
Plugging in the values, we get:
Number of moles = 1.204 x 10^24 / 6.02 x 10^23
Number of moles = 2
Therefore, the answer is 2.
Hence, is the correct answer.
