Answer:
To determine the number of moles in 1.204 x 10^24 molecules of bromine, we first need to know the molar mass of bromine. The molar mass of bromine is 79.904 g/mol.
Next, we can use Avogadro's number, which tells us that there are 6.022 x 10^23 molecules in one mole of a substance, to convert the number of molecules to moles.
1.204 x 10^24 molecules of bromine ÷ 6.022 x 10^23 molecules/mol = 19.99 moles of bromine
Therefore, there are approximately 19.99 moles in 1.204 x 10^24 molecules of bromine.
