How many molecules of glucose (molecular mass 180 daltons) would be present in one mole?

Question

I'm having a lot of difficulty understanding moles and converting them. Can anyone explain?

a. 24

b. 342

c. 23 * 10^14

d. 180 * 10^14

e. 6.02 * 10^23

Answer 1

Your answer would be 6.02 * 10^23....e

You must remember that Plank's constant always states that in one mole of a substance, there are exactly 6.02 * 10^23 molecules no matter what the substance is.
