Question

Find the total number of atoms present in 18 ml water (density of water -1g/ml) ​

Answer 1

Answer:

Mass of 18 mL of water

=(18mL)×(1gmL−1)=18g

18g of water =6.02×1023 molecules of H2O

1 molecule of water = 10 electrons

∴6.02×1023 molecules of water

=6.02×1023×10 electrons

=6.02×1024 electrons
