Question

How many atoms are present in 9 molecules of NH4CN?

Answer 1

Answer:

5.418x10^24 atoms

Explanation:

1mole of a substance contains 6.02x10^23 atoms.

From the above, it means that 1mole of NH4CN contains 6.02x10^23 atoms.

Therefore, 9 moles of NH4CN will contain = 9 x 6.02x10^23 = 5.418x10^24 atoms
