Question

How exactly do you get this result? (moles and particles)

Answer 1

I have been trying to figure this out. I am looking at some chemistry examples but I cannot get how they got that result. This wasn't explained.

Answer 2

If you have 1.50 moles of ammonia (NH3), how many atoms of hydrogen do you have?

Answer 3

1.50 Moles x 6.022 x 10^23/1 mole = 9.03 * 10^23

Answer 4

I get this so far, but this is where I get confused

Answer 5

3 x (9.03 * 10^23 particles) = 2.71 * 10^24

Answer 6

How did they get to this last entry?

Answer 7

the formula of ammonia tells you that you have ONE nitrogen atom and THREE hydrogen atoms (PER MOLECULE)

Answer 8

so one mole of ammonia MOLECULES contains THREE MOLES of hydrogen atoms

Answer 9

Yes I get all of that. However, what I'm stuck on is that I used simple math to calculate what: 3 * (9.03 * 10^23 particles) would be, but it just doesn't equal: (2.71 * 10^24)

Answer 10

i don't know where you're confused, because it does

Answer 11

Can you tell me how to do it just in case I am missing a step?

Answer 12

3 * 9.03 = 27.09 (or 27.1)

Answer 13

add in the scientific power and you get \[27.1*10^{23}\]

Answer 14

See mine says 27.1 * 10^24

Answer 15

an extra zero

Answer 16

no, it says \(2.71*10^{24}\), which is equal to \(27.1*10^{23}\)

Answer 17

27.1 * 10^24 is what this example says

Answer 18

then the example is off by a power of 10

Answer 19

No really, this example says 27.1

Answer 20

They must've made a mistake

Answer 21

then it's wrong

Answer 22

Well thanks anyways for clearing this up

Answer 23

Yeah. Thanks again
