Question

What is the mass of 6×1022 zinc atoms?

Answer 1

Answer:6.5g

Explanation:

Given:-

No.of zinc atoms=6*10^22

We know,

Molecular mass of zinc=65(approx)

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

Through the formula:-

No.of atoms =no.of moles*Avogadro's no.

Therefore, Putting the values

6*10^22=x/65*6*10^23

(After calculation)

We will get=6.5g
