Question

Calculate the number of moles for the 3.011 * 10 to power 24 number of he atoms.

Answer 1

Answer: 5 moles

Explanation:moles = no of atom/ avogadro number

Answer 2

The number of moles for the number of Helium atoms is 5.

Explanation:

It is given that,

Number of atoms are $3.011\times 10^{24}$

Let there are n number of moles. It is given by :

$n=\dfrac{no\ of\ atoms}{avagadro\ number}$

$n=\dfrac{3.011\times 10^{24}}{6.023\times 10^{23}}$

n = 4.99

or

n = 5

So, the number of moles for the number of Helium atoms is 5. Hence, this is the required solution.
