Question

5.080 x 1016 molecules of hydrogen (gas) to moles

Answer 1

Take note that one mole of any substance is equal to 6.02 x 10^23 molecules. Thus in converting 5.080 x 10^16 molecules of hydrogen to moles, just divide it with the Avogadro’s number. The answer would be 8.44 x 19^-8 moles...

i think that's it :P :)
