divide this number by avagadros number to get moles.
(5.16x1024)/(6.02x1023)=8.57mol of H2O
as there are 3 atoms in each molecule there are 3x8.57=25.7 moles of atoms.

How many dozen atoms of hydrogen are present in a dozen molecules of h20?
2 dozen
How many moles of water contain 2.60 X 1023 molecules of water?
follow the avagardo number here, 2.60x10^23 molecules of H2O X 1mole ------- 6.02x10^23 molecule of H2O ( molecule of H2O cancel and just remain with mole ) so, 2.60x10^23 ----------------- moles 6.02x10^23 your final product wii be 0.43 mole of H20 source me rata mokai
How many molecules are present in 3 h20?
H2O consists of two Hydrogen and one Oxygen. Three sets of these would mean 9 atoms in your three molecules of water.
Which molecules have three atoms that do not fall in a straight line?
Water - H20
What is the limiting reagent in a reaction?
The limiting reagent in a reaction is the reactant that runs out first. For example, if you are reacting 10 moles of HCl and 5 moles of NaOH, you will get 5 moles of H20, 5 moles of NaCl, and 5 moles of HCl, because the remaining HCl had nothing to react with. Therefore, the NaOH is the limiting reagent.
How many molecules are in 4.21 grams of water?
45 grams H20 x (1 mole H20/18 grams H2O) x (6.02E23 molecules H20/1 mole H2O) the grams H2O and moles H2O cancel out. When you punch it into your calculator, the answer comes out to: =1.505E24 molecules H2O
How many molecules of h20 are in 2.43 mol of h20?
A mole of any substance is 6.02214179×1023 (just use 6.022) molecules of it. So 1.23 moles of any substance (including water) is 1.23 x 6.022 x 1023 molecules, whatever that is...
How many molecules in 0.4 moles of h20?
Each mole of a substance contains 6.022 E23 molecules or atoms of that substance. Four moles of H2O will contain 2.4088 E24 molecules.
How many molecules of water H20 contain2.60x1023molecules of water?
Of course, 6,022.10e23 molecules.
Are h20 and ozone both molecules?
Yes, H2O and Ozone both are molecules. H20 is water.
How many moles of oxygen gas are needed to make 4 moles of water?
4 moles of oxygen atoms are present in 4 moles of H2O
How many atoms are in 6h2o?
