Question

If you have a tank that contains 3.5 x 10^24 molecules of propane (C,H₂), how many moles of propane do you

have?

Answer 1

Answer: Avogadro's number is 6.022 x 10^23, which represents the number of particles (atoms or molecules) in one mole of a substance. Therefore, to calculate the number of moles of propane from the given number of molecules, we need to divide the number of molecules by Avogadro's number:

Explanation: number of moles = number of molecules / Avogadro's number

number of moles = 3.5 x 10^24 / 6.022 x 10^23

number of moles = 5.81

Therefore, the tank contains 5.81 moles of propane.
