Question

How many moles are 9.033*10^24atoms of helium

Answer 1

Answer:

14.99 moles

Explanation:

We must know that, Avogadro's number is numerically equal to 6.023 * 10^23 !

It is a fact that,

1 mole of any element or molecule = The Avogadro's number

=> 1 mole of Helium = 6.023 * 10^23 particles(or atoms)

The above sentence can also be written as,

=> There are 6.023 * 10^23 particles in 1 mole of Helium.

=> There is 1 particle in 1/(6.023*10^23) moles of Helium.

=> There are 9.033 * 10^24 particles in { 1/(6.023*10^23) * 9.033 * 10^24 } moles of Helium.

=> There are 9.033 * 10^24 particles in 1.499 * 10 moles of Helium.

=> There are 9.033 * 10^24 particles in 14.99 moles of Helium.

Hence,

14.99 moles of Helium = 9.033 * 10^24 particles of Helium
