Answer:

approx. 5.0 x10^24 atoms

Step-by-step explanation:

The molar mass of water is 18.02g/mol

50 grams of water contains 50g x 1 mole/18.02g moles of water

2.775 moles H2O

1 mole of H2O contains 6.022 x 10^23 molecules of water

2.775 moles of H2O contains 2.775 x 6.022 x 10^23 molecules of H2O

= 1.6711 x 10^24 molecules of H2O

1 molecule of H2O contains 3 atoms

Therefore 1.6711 x 10^24 molecules contains 1.6711 x 10^24 x 3 atoms

= approx. 5.0 x10^24 atoms
