# How is scientific notation used in chemistry?

Mar 29, 2018

#### Answer:

Is used to express numbers that are too big to write.

#### Explanation:

Scientific annotations is when you have such a bigger number that you cannot write it. Is like simplifying.
For example we have 0.00000345.
With scientific annotations is: 3. $3.45 \cdot {10}^{-} 6$. This because you times the number by 10 six times, making sure a decimal number is over the point (.)

Hope this helps and good luck!!
