Question

Calculate the number of moles of nitrogen gas that contains 0.03011x1023 molecules.


​

Answer 1

Correct question:-

Calculate the number of moles of nitrogen gas that contains 0.03011×10²³ molecules.

Given:-

→Number of molecules = 0.03011×10²³

To find:-

→Number of moles

Solution:-

•Avogadro number = 6.022×10²³

No of moles:-

= No of particles/Avogadro number

= 0.3011×10²³/6.022×10²³

= 0.3011/6.022

= 0.05 mole

Thus is the required number of moles of nitrogen gas is 0.05.

Some Extra Information:-

Number of moles:-

= Given mass/Molar mass (1)

= No of particles/Avogadro number (2)

Number of atoms:-

= No of moles × Avogadro number

Number of molecules-

= No of moles × Avogadro number
