Question

Mass of 1*10^25 molecules of water

Answer 1

Answer:

We know that one mole of any substance comprises 6.022×10^23 particles. We can call the value of 6.022×10^23 as Avogadro number (or) Avogadro constant and is represented by the symbol NA. We can calculate the mass of one molecule of water using the molar mass of water and Avogadro number.
