Find the molecules in 75.0 liters of F2 at STP

20.16 × 10^(23) molecules

Explanation:

We know that At STP, 22.4 L of any substance = 6.02 × 10^(23) molecules

Thus;

75 L of F2 at STP will give;

(75 × 6.02 × 10^(23))/22.4 = 20.16 × 10^(23) molecules

Number of molecules in 75.0 liters of F2 at STP = 20.16 × 10^(23) molecules

the correct answer would be d. hope this !

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
