Question

I. Calculate the number of moles in the following.

a. 7g of N2.

b. 3.01×10^22 molecules of CO2.​

Answer 1

Answer:

B)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

= 6.02 × 10²³.

(Avogadro Number is taken as 6.02 × 10²³ )

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