How many atoms are in 3.93 mol of O2?
I did the following but did not get the right answer.
3.93 mol O2 X 6.022x10^23/1 mol O2
To find the number of atoms in a given amount of a substance, you can use Avogadro's number, which is approximately 6.022x10^23 atoms/mol. However, in your calculation, it seems there was a mistake in the formula you used.
The correct calculation should be:
3.93 mol O2 × (6.022x10^23 atoms/mol)
By multiplying the given number of moles (3.93 mol) by the conversion factor (6.022x10^23 atoms/mol), you can find the number of atoms in 3.93 mol of O2.
Let's plug in the values:
3.93 mol O2 × 6.022x10^23 atoms/mol ≈ 2.366x10^24 atoms
So, the correct answer is approximately 2.366x10^24 atoms.
