How many molecules are in 0.80 mol of NaCl.

There are molecules in 0.80 mol of NaCl.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.

As 1 mole of contains =  molecules

0.80 mole of contains = molecules

Thus there are molecules in 0.80 mol of NaCl.
