## Chem – Scientific Notation Part 2

What sections should I know before attempting to learn this section?

How do we go from a non-scientific notation number to a scientific notation number?

What happens if we go in the reverse direction? Let’s take a non-scientific notation number and turn it into scientific notation.

VIDEO Scientific Notation Demonstrated Example 3: Convert this non-scientific notation number below into scientific notation.

0.00000000873

What is the first non-zero number we encounter as we go from left to right above?

What are all the significant figures or numbers after and including 8?

Where would a decimal point go to make those digits into a number between 1 and 10?

How many places do we have to move our decimal from our original number to get 8.73?

Therefore, what is the exponent on the 10?

Is the exponent positive or negative?

Answer: Negative (because we started off with a small number)

VIDEO Scientific Notation Demonstrated Example 4: Convert this non-scientific notation number below into scientific notation.

425000

What is the first non-zero number we encounter as we go from left to right above?

What are all the significant figures or numbers after and including 4?

Where would a decimal point go to make those digits into a number between 1 and 10?

How many places do we have to move our decimal from our original number to get 4.25?

Therefore, what is the exponent on the 10?

Is the exponent positive or negative?

Answer: Positive (because we started off with a large number)
