Question

if you have one mole of h2o molecules (6.02 x 10^23 molecules of water) how many moles of hydrogen (h) atoms do you have? hint: remember you have two atoms of hydrogen in every molecule of water. by the way 18 grams of water is about 18 ml (0.018 l) 1 mole of h atoms 2 moles of h atoms 18 moles of h atoms

Explanation:

Step1: Analyze the water molecule structure

A water molecule ($H_2O$) has 2 hydrogen atoms. So, for each mole of $H_2O$ molecules, we consider the number of H atoms per molecule.

Step2: Calculate moles of H atoms

If we have 1 mole of $H_2O$ molecules, and each $H_2O$ has 2 H atoms, then the moles of H atoms = 1 mole of $H_2O$ × 2 H atoms per $H_2O$ molecule = 2 moles of H atoms.

Answer:

2 moles of H atoms (corresponding to the option: 2 moles of H atoms)
