How many oxygen atoms are present in 5.2g of 02?

Answer 1

Well, honey, if you're talking about 5.2g of O2, then we need to remember that oxygen comes in pairs in O2 molecules. So, one mole of O2 weighs 32g and contains 6.022 x 10^23 molecules, which means 5.2g of O2 would contain about 1 x 10^23 oxygen atoms. Hope that clears the air for you!

Answer 2

Well, isn't that a happy little question! To find out how many oxygen atoms are in 5.2g of O2, we first need to determine how many moles of O2 are present. Then, we use Avogadro's number to find the number of molecules, and since each O2 molecule has 2 oxygen atoms, we can calculate the total number of oxygen atoms. Just remember, there are no mistakes, only happy little accidents in chemistry!

Answer 3

There are 0.325 moles of O2 in 5.2g, which contains 2 oxygen atoms per molecule of O2. Therefore, there are 0.65 moles of oxygen atoms. Since one mole of O2 contains 2 moles of oxygen atoms, there are 1.3 moles of oxygen atoms in 5.2g of O2.

Answer 4

Amount of oxygen = 5.2/32.0 = 0.163mol

Number of oxygen molecules = 0.163 x 6.02 x 1023 = 9.78 x 1022

Number of oxygen atoms = 2 x 9.78 x 1022 = 1.96 x 1023
