Question

A substance contains 18.066 x 1023 molecules of water. Calculate the number of moles present in it

Answer 1

Answer:

3

Explanation:

n = N/ avogadro no = (18.066 * 10^23)/ (6.022 * 10^23) = 3

Hope it's clear

Answer 2

Answer:

No of moles  =  3

Explanation:

Avogadro number  =   6.022 x 10^23

No of  moles           =  18.066 x  10^ 23  /    6.022 x  10^ 23   =   3.

Hence 3  moles.
