This connection is then used to change over various H2O particles to grams by the proportion: mass of X atoms of H2O/X particles mass of a mole of H20 atoms/6.022 x 1023 particles Tackle for X atoms of H2O X atoms of H2O ( 6.022 x 1023 H2O particles )/( mass of a mole H2O  · mass of X atoms of H2O Enter the qualities for the question:X atoms of H2O ( 6.022 x 1023 H2O particles )/( 18.02g  · 1 g )X atoms of H2O 3.35 x 1022 particles/gram There are 3.35 x 1022 H2O atoms in 1 g of H2O. Our snowflake gauges 1 mg and 1 g 1000 mg. X atoms of H2O 3.35 x 1022 particles/gram  · (1 g/1000 mg )X particles of H2O 3.35 x 1019 atoms/mg Answer There are 3.35 x 1019 H2O atoms in a 1 mg snowflake. Avogadros Number Problem Key Takeaways Avogadros number is 6.02 x 1023. It is the quantity of particles in a mole.You can utilize Avogadros number to change over among mass and the quantity of atoms of any unadulterated substance.If you are given the mass of an example, (for example, a snowflake), convert the mass to moles, and afterward use Avogadros number to change over from moles to particles.
