How many helium atoms are there in a helium blimp containing 541 kg of helium?
Asked by maham237 @ in Chemistry viewed by 350 People
Answered by maham237 @
The answer is 8.13 x 10²⁸ atoms.
First
we calculate the number of moles using
the molar mass.
molar mass of helium = 4 g/mol.
it means that 1 mole of helium atoms weighs 4 gram.
Now we have 540 kg of helium =540000 grams
Number
of moles in 540000 grams;
540000 / 4 =135000 mol
Now in one mole there is 6.02 x 10²³ atoms
So, in 135000 mol there is;
135000 x 6.02 x 10²³ = 8.13 x 10²⁸atoms
