Question

Calculate the number of moles of so2 present in 3.01 x 10^23 molecules of the gas

Answer 1

Explanation:

Given that the no. of molecules of CO₂ is 3.01 × 10²².

We're given to find the no. of moles in this no. of CO₂.

We may know that,

No. of moles = Given no. of molecules / Avogadro Number

And we know Avogadro Number = 6.02 × 10²³.

(Avogadro Number is taken as 6.02 × 10²³ according to the no. of molecules given in the question.)

So no. of moles equals,

(3.01 × 10²²) / (6.02 × 10²³) = 1 / 20 = 0.05 mole
