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 = (1)/(3)\\\\Number\ of\ hydrogen\ atoms = 3 - (1)/(3) = (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 = (8)/(3) * 114\\\\Number\ of\ hydrogen\ atoms = 8 * 38\\\\Number\ of\ hydrogen\ atoms = 304`

Thus number of hydrogen atoms are 304
