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
