Question

There are 5.7 moles of helium in a container. How many atoms of He does the container hold?

Answer 1

3.43 x 10²⁴atoms

Step-by-step explanation:

To solve this problem, the mole concept will play a very vital role.

We have been given that:

number of moles = 5.7moles of He;

So;

We know that:

1 mole of any substance contains 6.02 x 10²³ atoms

5.7 moles of He will contain 5.7 x 6.02 x 10²³ atoms = 3.43 x 10²⁴atoms
