Question

how much positive and negative charge is there in 500gm of water​

Answer 1

Answer:

Generally,the mass of water contained in cup is 250g.The molecular mass of water is 18g per mol.

Number of molecules present in a cup of water,n=6.022×10^23×250/18 =8.36×10^24

Each molecule of water(H2O) contain 2+8=10 electrons as well as proton.

Total no. of electrons or protons present in a cup of water,n’=n×10=8.36×10^25

Total negative or positive charge =

q=n’e

=8.36×10^25×1.6×10^-19 C=1.33×10^7 C.
