Question #fcd51

Answer 1

2.7692 x `10^24` atoms.

Explanation:

Each mole of substance contains 6.02 x `10^23` component parts, in this case water molecules.

If you have 2.3 moles of water you will have 2.3 x 6.02 x `10^23` which is 1.3846 x `10^24` 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 `10^24` = 2.7692 x `10^24`.
