Question

21. Calculate the no. of moles present in 12.044 X 10²³ molecules of oxygen atom.​

Answer 1

Answer:2.00066

Explanation: the formula of finding moles is

No of molecules = moles ×Na (Avogadro's number)

Moles= no .of molecules /Na

Moles = 12.044×10²³ / 6.02×10²³

Moles= 2.0006 moles

Answer 2

Answer:

Explanation:

No of molecules = mole(s) ×Na (Avogadro's number)

Moles= no .of molecules /Na

Moles = 12.044×10²³ / 6.02×10²³

Moles= 2.0006 moles
