There are 9.23 x 1023 molecules of water in a beaker, how many moles are there?

Answer 1

Answer: There are 1.53 moles present in
`9.23 * 10^(23)` molecules of water in a beaker.

Step-by-step explanation:

According to the mole concept, there are
`6.022 * 10^(23)` molecules present in 1 mole of a substance.

So, number of moles present in
`9.23 * 10^(23)` molecules are calculated as follows.

`Moles = (9.23 * 10^(23))/(6.022 * 10^(23))\\= 1.53 moles`

Thus, we can conclude that there are 1.53 moles present in
`9.23 * 10^(23)` molecules of water in a beaker.
