Question

How many atoms are present in 18grams of water?

Answer 1

Answer:

3 atoms

Avogadro's number) of particles. So one mole of water contains 6.022×10^23 number of water molecules. We know that every water molecule is made up of two hydrogens and one oxygen which means that every water molecule contains 3 atoms. So, to get number of atoms in 18g of water, we will multiply Avogadro's number by 3.
