Question

Is the value of Avogadro's number is changed to 1.0 into 10 to 20 what would be the molecular mass of Nitrogen gas

Answer 1

28gms of N2= 6.023*10^23 molecules

so for 10^20 molecules of N2,

=28/(6.023*10^3)

=4.65*10^-3 gms of N2

=4.65mg of N2

Answer 2

Answer:

28 g of N2= 6.022×10^23 molecules

Given changed avogadros number =1.0×10^20.

So, 1.0×10^20 molecules=28÷6.022×10^3

answer=4.6×10^-3 amu
