Estimate the number of electrons in 100 g water. How much is the total negative charge on these electrons?

Explanation

No. of electrons in `18 gms of H_2O`
` 6.023xx1023xx10 `
` =6.023xx10^24 `
No. of electrons in `100 gms of H_2O`
` =0.334xx10^26 `
` =3.34xx10^25 `
` Total charge=3.34xx10^25xx1.6xx10^-19 `
` =5.34xx10^6C`
