Question:
Positive and negative charge in 18 cc of water is ??
Answer:
Mass of water = 180 g
Molecular weight of water = 18
Hence, number of molecules in 180 g of water = 6.023 * 1023 * 180 / 18 = 6.023 * 1024
Each molecule of water contains 10 electrons, So number of electrons = 6.023 * 1024 * 10 = 6.023 * 1025
We know that q = ne = 6.023 * 1025 * 1.6 * 10-19 C = 9.6368 * 106 C
