How many oxygen atoms are present in 5.2g of O2 (Aw O=16)?

Answer 1

Oh, what a lovely question! To find the number of oxygen atoms in 5.2g of O2, we first need to calculate the number of moles of O2 using its molar mass (32g/mol). Then, we use Avogadro's number (6.022 x 10^23) to find that there are approximately 1.63 x 10^23 oxygen atoms in 5.2g of O2. Just imagine all those tiny atoms dancing together in harmony!

Answer 2

To determine the number of oxygen atoms present in 5.2g of O2, you first need to calculate the number of moles of O2 using the molar mass of O2 (32g/mol). Next, you use Avogadro's number (6.022 x 10^23) to convert moles of O2 to oxygen atoms. Therefore, 5.2g of O2 contains 0.1625 moles of O2, which is equivalent to 9.79 x 10^22 oxygen atoms.
