Answer: There are
4.81* 10^(23) molecules in 0.80 mol of NaCl.

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
6.023* 10^(23) of particles.

As 1 mole of
NaCl contains =
6.023* 10^(23) molecules

0.80 mole of
NaCl contains =
(6.023* 10^(23))/(1)* 0.80=4.81* 10^(23) molecules

Thus there are
4.81* 10^(23) molecules in 0.80 mol of NaCl.
