How much positive and negative charge is there in a cup of water

Text Solution

Verified by Experts

Let us assume that the mass of one cup of water is 250 g the molecular mass of water is 18 g thus one mole of water is 18 g therefore the number of molecules in one cup of water is `(250//18)xx6.02 xx10^(23)` each molecule of water contains two hydrogen atoms and one oxygen total negative charge has the same magnitude it is equal to `(250//18)xx6.02 xx10xx1.6 xx10^(-10^(-19) C=1.34 xx10^(7)C`
