How many atoms are in 1l of water

1.	How many atoms are in 1l of water
Answer» One liter of water has 1000 grams.Number of moles is {tex}\\frac{1000}{18}{/tex} = 55.556 moles.The number of molecules is therefore 6.022{tex}\\times{/tex}1023{tex}\\times{/tex} 55.556 = 3.346 {tex}\\times{/tex}\xa01025 molecules.The number of atoms is 3 times larger because each molecule has three atoms, so there are 1.0038{tex}\\times{/tex}1026 atoms in a liter of water.<br>1L=1000gH2OMass of 1 mole H2O= 12+16=18gNo. Of moles in 1000gH2O= 1000/18=50.5moles(approx)No. of atoms present in 50.5 moles=50.56.022*10²³=???answer
