Question

Calculate the number of molecules in 12.3 moles of SO3

Answer 1

To calculate the number of molecules in 12.3 moles of SO3, we can use the Avogadro's number, which is the number of atoms or molecules in one mole of a substance. Avogadro's number is approximately 6.022 x 10^23 atoms or molecules per mole.

To calculate the number of molecules in 12.3 moles of SO3, we can multiply Avogadro's number by the number of moles of SO3:

Number of molecules = Avogadro's number x moles of SO3

Number of molecules = 6.022 x 10^23 x 12.3

Number of molecules = 7.34 x 10^24

So there are approximately 7.34 x 10^24 molecules in 12.3 moles of SO3.
