Question

How many moles are in 8.30x10^23 molecules of H2o

Answer 1

You multiply avogadro's number to what you were given.
8.30x10^23 * 6. 0221409x10^23
=1.357*10^25

That should be the right answer but I'm not sure. It has been awhile since I have done this.

Answer 2

Answer: 1.38 moles

Explanation: According to Avogadro's law, 1 mole of every substance contains Avogadro number of particles (atoms, molecules or ions) i.e.
`6.023* 10^(23)` particles.

Given : 1 mole molecule of water contains
`6.023* 10^(23)` molecules of water.

`6.023* 10^(23)` molecules are present in = 1 mole

`8.30* 10^(23)` molecules will be present in =
`(1)/(6.023* 10^(23))* 8.30* 10^(23)=1.38 moles`

Thus
`8.30* 10^(23)` molecules is equal to 1.38 moles.
