When we convert a number to scientific notation, we begin by writing a the first (non-zero) digit in the number. If the number contains more than one digit, we write a decimal point, followed by all of the remaining digits.

…**Convert the following numbers into scientific notation:**

- 93,000,000.
- 708,010.
- 0.000248.
- 800.0.

## How do you write scientific notation in chemistry?

Scientific notation is a more convenient way of writing very small or very large numbers. The general representation for scientific notation is **a×10b a × 10 b** (where “b” is an integer and “a” is any real number).**Examples of scientific notation:**

- 0.0001 = 1 x 10.
^{–}^{4} - . 0256 = 2.56 x 10.
^{–}^{2} - 4759000 = 4.759 x 10. …
- 5000 = 5 x 10.

## What is scientific notation used for in chemistry?

There are two reasons to use scientific notation in chemistry. The first is **to reveal honest uncertainty in experimental measurements**. The second is to express very large or very small numbers so they are easier to read.

## How do you write scientific notation?

Scientific notation is a way of writing very large or very small numbers. **A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10**. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.

## What is scientific notation in science?

Definition of scientific notation

: **a widely used floating-point system in which numbers are expressed as products consisting of a number between 1 and 10 multiplied by an appropriate power of 10** (as in 1.591 × 10^{−}^{20})

## How do you write 0.82 in scientific notation?

A positive number is written in scientific notation if it is written as a×10n a × 10 n where the coefficient a is 1≤a<10 1 ≤ a < 10 , and n is an integer.
