Question

How many molecules are in 2.3 moles of h2o

Answer 1

Each mole of substance contains 6.02 x 1023 component parts, in this case water molecules.

If you have 2.3 moles of water you will have 2.3 x 6.02 x 1023 which is 1.3846 x 1024 molecules.

Each molecule contains 2 hydrogen atoms, so the total number of hydrogen atoms in 2.3 moles of water will be 2 x 1.3846 x 1024 = 2.7692 x 1024.
