Question

How many molecules are there in 4.00 moles C3H6O3


HELP!

Answer 1

`2.4088 * 10^(24) \text { molecules }` are there in
`4.00 \text { moles } C_(3) H_(6) O_(3)`

Step-by-step explanation:

One mole =
`6.022 * 10^(23)` (Applicable to the substances like ions, molecules, or atoms). This specified number is called as Avogadro's constant or number. This idea helps us to convert number of moles of a substance to the number of molecules, multiply moles by Avogadro's number,
`6.022 * 10^(23)`

Given:

`4.00 \text { moles } C_(3) H_(6) O_(3)`

To find the number of molecules in it

By using Avogadro’s number, convert given moles into molecules as below,

`\text { 4.00 moles } C_(3) H_(6) O_(3) * \frac{6.022 * 10^(23) \text { molecules }}{1 \text { mole } C_(3) H_(6) O_(3)}`

By solving the above, we get

`Number of molecules of $C_(3) H_(6) O_(3)=24.088 * 10^(23)$`

`Number\ of\ molecules\ of\ C_(3) H_(6) O_(3)=2.4088 * 10^(24)\ molecules\ C_(3) H_(6) O_(3)`
