Question

How many atoms of helium will make 4 moles of He​

Answer 1

Answer:

1 mole of Helium = weight of helium/4weight of helium= 1*4=4 grams 1 mole of Helium contains 6.023*10>23 (Avogadro Number)atoms.

Explanation:

Answer 2

Given:

No of moles of helium = 4

To Find:

The no of atoms of helium in 4 moles of it.

Calculation:

- Helium is a noble gas, so it exists as single atoms.

- The no of atoms in 1 mole of He = 6.022 × 10²³

⇒ The no of atoms in 4 moles of He = 4 × 6.022 × 10²³

⇒ n = 2.4088 × 10²⁴

- So, the no of atoms in 4 moles of helium is 2.4088 × 10²⁴.
