Question

There are 3.76 x 10 to the power of 22 atoms in 1 gram of oxygen. How many atoms are there in 600 grams of oxygen? Write your answer in scientific notation.

A.BCD x 10 to the power of E

Answer 1

2.256 x 10 to the power of 25

Explanation:

There are 3.76 x 10 to the power of 22 atoms in 1 gram of oxygen

So, there are x atoms in 600 grams of oxygen

Using the ratio and proportional

So, the number of atoms = 600 * 3.76 x 10 to the power of 22 =

`= 6*10^2 * 3.76 * 10^(22)\\=6*3.76 * 10^2*10^(22)\\=22.56 * 10^(24)\\=2.256 * 10 * 10^(24)\\=2.256 * 10^(25)`

So, the answer in scientific notation as A.BCD x 10 to the power of E

Will be 2.256 x 10 to the power of 25
