Estimate the number of electrons in 100 g of water. How much is the total negative charge on these electrons ?
No. of electrons of 100 g water =10x100/18=55.5 Nos
Total charge = 55.5
No. of electrons in 18 g of H2O = 6.023 × 1023 × 10 = 6.023 × 1024
No. of electrons in 100 g of H2O
Total charge = 3.34 × 1025 × 1.6 × 10–19 = 5.34 × 106 c
