Question

Total no. Of ptotons in 36 ml of water at 4°C

Answer 1

Answer:

One mole of water = 18 g = 18 ml (density of water at 4 degrees C = 1g/ml); 18 ml of water = 1 mole. 36 ml of water = 2 moles. Now, number of H2O molecules = number of moles * Avagardo's Number = 2 * 6.022 * 10^23 = 12.044 * 10^23 Now, we'll find how many protons does 1 molecule of H2O has - 2 of hydrogen + 8 of oxygen = 10 protons. Therefore, 36 ml of water has protons = 12.044 * 10^23 * 10 = 12.044 * 10^24 protons.
