Question

Calculate the number of moles with formula 1.51 to 10 power 23 molecules of water

Answer 1

Answer:

0.25 mol

Explanation:

n= N/NA

N= the number of molecules

NA= the avogadro's number

n= (1.51×10^23)/(6.02×10^23)=0.25 mol

Answer 2

Answer:

Converting between molecules and moles is done by either multiplying by or dividing by Avogadro's number:

To go from moles to molecules, multiply the number of moles by 6.02 x 1023.

To go from molecules to moles, divide the numbers of molecules by 6.02 x 1023
