Solution

## The correct option is C 6.02×1024Density of water (given)=1ℊ/㎖∴18㎖ of water=18ℊ of waterMolecular mass of wwater=18ℊ/㏖1 molecule of H2O contains 10 electrons in total.[2 electrons from 2H and 8 electrons from O]Total number of electrons=(No. of electrons in 1 molecule) × (Total no. of molecules)=10×(Avogadro's number)⇒6.02×1024 electrons.Hence, the correct option is C
