Question 1 Report

How many moles of oxygen would contain 1.204 x 1024 molecules?
[Avogadro's constant (NA) = 6.02 x 1023]
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.
