Answer:
4.51 moles of carbon dioxide
Step by step explanation
To calculate the number of moles in 4.5 molecules of carbon dioxide, we need to use the Avogadro's number, which is the number of particles in one mole of a substance.
Avogadro's number (Nᴀ) is 6.022 x 10²³ particles per mole.
Therefore, we can calculate the number of moles of carbon dioxide as follows:
Number of moles = Number of particles / Avogadro's number
Number of particles of CO2 = 4.5 molecules x 6.022 x 10²³ particles per mole
= 2.711 x 10²⁴ particles
Number of moles of CO2 = 2.711 x 10²⁴ particles / 6.022 x 10²³ particles per mole
= 4.51 moles (rounded to two decimal places)
Therefore, 4.5 molecules of carbon dioxide is equal to 4.51 moles of carbon dioxide
