How many grams are there in 3.4 x 10^24 atoms of He?
Lelechka [254]

Given :

Number of He atoms, n = 3.4\times 10^{24} atoms.

To Find :

How many grams are their in given number of He atoms.

Solution :

We know, molecular mass of He is 4 g. It means that their are 6.022 \times 10^{23} atoms in 4 g of He.

Let, number of gram He in 3.4\times 10^{24} atoms is x , so :

x = \dfrac{3.4\times 10^{24}}{6.022\times 10^{23}}\times 4\\\\x =  $$22.58\ g

Therefore, grams of He atoms is 22.58 g .
