The number of hydrogen atoms are 304

<em><u>Solution:</u></em>

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

<em><u>Therefore, number of hydrogen atoms is given as:</u></em>

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

Quation that show an estimate of 7,203+299
Dmitry [639]

The two numbers are very near 7200 and 300. The sum of those is a good estimate of your sum:

... 7200 + 300 = 7500

_____

If you're taught methods of addition that include "make a ten" or "make a hundred", you know you can "borrow" a 1 from 7203 (making it 7202) and loan that 1 to 299 to make it 300. Now, you know your sum is exactly 7202+300 = 7502, with no estimation necessary.
