1 mole is the amount of a substance, representing number of particles (molecules or ions or atoms) present in it.
Water's Molecular mass is 18.
18g water contains 6 x 10²³ atoms.
So 1g contains 6 x 10²³/18 atoms.
therefore, 45g water contains (6x10²³ x 45)/18 atoms.
which is equal to 15 x 10²³ atoms.
Note that the 6 x 10²³ is Avogadro's number, it is fixed.
