How many helium atoms are there in a helium blimp containing 536 kg of helium? n = atoms?
Mariulka [41]

Answer:- 8.07*10^2^8atoms

Solution:- It is a unit conversion where it asks to convert kg of He to atoms. We need to convert kg to grams, grams to moles and finally moles to atoms.

We know that, 1 kg = 1000 g

Molar mass of He is 4.0 grams per mole and 1 mole of an atom equals to Avogadro number of atoms.

The set up would be as given below:

536kg(\frac{1000g}{1kg})(\frac{1mole}{4g})(\frac{6.02*10^2^3atoms}{1mole})

= 8.07*10^2^8atoms

So, there are 8.07*10^2^8atoms of He in it's 536 kg.
