Question

A water molecule is made up of three Adams. 1/3 of the atoms are oxygen and the remaining Adams are hydrogen. If there are 114 water molecules, how many hydrogen Adams are there? Show your work.

Answer 1

The number of hydrogen atoms are 304

Solution:

Given that a water molecule is made up of three atoms

Number of atoms in water molecule = 3 atoms

1/3 of the atoms are oxygen and the remaining Adams are hydrogen

$Number\ of\ oxygen\ atoms = \frac{1}{3}\\\\Number\ of\ hydrogen\ atoms = 3 - \frac{1}{3} = \frac{8}{3}$

There are 114 water molecules

8/3 of water molecule is hydrogen

Therefore, number of hydrogen atoms is given as:

$Number\ of\ hydrogen\ atoms = \frac{8}{3} \times 114\\\\Number\ of\ hydrogen\ atoms = 8 \times 38\\\\Number\ of\ hydrogen\ atoms = 304$

Thus number of hydrogen atoms are 304
