1.58*10^-23 moles of flourine are there in 19 atoms of it.

According to the Avogadro's Law, we know that 1 mole of any substance should contain Avogadro number of particles.

So, 2*6.023*10^23 atoms are present in 1 mole of flourine. [F is bimolecular]

By unitary method, 1 atom should be present in = (1/2*6.023*10^23) moles of flourine.

Similarly, 19 atoms should be present in = (19/2*6.023*10^23) moles

= 1.58*10^-23 moles of flourine
