Question

How many moles are in 9.35 x 10^24 molecules of
molecular hydrogen?

Answer 1

One mole of a substance contains 6.022 x 10^23 particles (Avogadro's number).

Therefore, to find the number of moles in 9.35 x 10^24 molecules of molecular hydrogen, we need to divide this number by Avogadro's number:

moles = (9.35 x 10^24 molecules) / (6.022 x 10^23 molecules/mol)

moles = 15.5 mol (rounded to two decimal places)

Therefore, there are 15.5 moles in 9.35 x 10^24 molecules of molecular hydrogen.
