Question 2.
One molecule of butane (C4H10) would have a mass, in grams, of?

I looked at the answer and the explanation they used but I still don't understand how they got 58/( 6 x 10^23)

Help?

1 mol weighs 58 gram. In 1 mol, there are 6E23 molecules. So split the 58 into 6E23 molecules, you get 58/( 6 x 10^23).

Remember that the mol is just a heap of molecules, not some magical number.

What schnappy said.

It's not asking for the mass of one mol, it's asking for the mass of a singular molecule, not a mole of molecules.

where n = no. of moles

Therefore, n = (no. of molecules)/(N_A)

Therefore,







Hope I helped.
