Question

find the mass of following 6.022×10^23 number of O2 molecules
​

Answer 1

Explanation:

No. of moles =no. of molecules/avogadro no.(6.022*10^23)

Now,in case of 6.022*10^23 molecules of O2

No.of moles =6.022*10^23/6.022*10^23=1

As,no. of moles = given mass/molar mass

1=mass/32g(O2)

Mass=32g
