How many moles are equivalent to 3.4 x 10^23 molecules of H2SO4?

To determine how many moles are equivalent to a specific number of molecules, you can use Avogadro's number, which is approximately 6.022 x 10^23 molecules per mole. The relationship between moles and molecules is established through this constant.

Starting with the given number of molecules (3.4 x 10^23), you would divide this number by Avogadro's number to find the number of moles:

Moles = (Number of molecules) / (Avogadro's number)

Plugging in the values:

Moles = (3.4 x 10^23 molecules) / (6.022 x 10^23 molecules/mole)

Calculating this results in:

Moles = 0.564 moles

This value can be rounded to 0.56 moles. Therefore, the correct answer indicates that 3.4 x 10^23 molecules of H2SO4 corresponds to approximately 0.56 moles.

The reasoning around why this particular choice is correct helps to solidify the grasp of mole calculations in chemistry, particularly in the context of understanding how to convert from molecules to moles using established constants such as Avogadro's number.
