Problem 7: If there are N₀ = 6.02 * 10²³ atoms in 4 gm of helium. What is the mass of one helium atom?

Solution

Given data:      No of helium atoms = 6.02 * 10²³

                            Mass of the above no of atoms = 4 g

Required:          Mass of 1 atom of helium atom

Now

This is the required result.
