Sagot :
Because you're turning moles into molecules, all you need to use is Avogadro's Number (6.022*10^23).
The equation would be: .400 mol N2O5/1 mol*6.022*10^23 molecules.
The answer, including significant figures, is 151 molecules.

Answer:
2.40 × 10²³ Molecules of N₂O₅
Explanation:
As we know 1 mole of any substance contains 6.022 × 10²³ particles (also called as Avogadro's Number). Therefore, the relation between moles and number of particles can be written as,
Moles = Number of Particles ÷ 6.022 ×10²³ Particles.mol⁻¹
For the molecules of Dinitrogen pentoxide (N₂O₅) it can be written as,
Moles = Number of Molecules ÷ 6.022 ×10²³ Molecules.mol⁻¹
Rearranging for Number of Molecules,
Number of Molecules = Moles × 6.022 ×10²³ Molecules.mol⁻¹
Putting value of Moles,
Number of Molecules = 0.400 mol × 6.022 ×10²³ Molecules.mol⁻¹
Number of Molecules = 2.40 × 10²³ Molecules of N₂O₅
