Question

Determine the number of atoms in a 52.0 gram sample of carbon, how would you set up the conversion?

Answer 1

@ganeshie8 @satellite73 @chmvijay

Answer 2

52g/(12g/mol) = # of moles.
Convert to atoms using avogadro's constant

Answer 3

@ECE is this the answer

Answer 4

Is this the answer

Answer 5

Avogadro's constant is atoms/mol so yes.

Answer 6

@chmvijay is this correct I don't quite get it

Answer 7

what is one mole of C? how much it weighs?

Answer 8

idk im so sorry I don't get this

Answer 9

one mole of any elements contains =6.023*10^23 of atoms of that element
ok

Answer 10

ok got it

Answer 11

so one mole of that element = atomic weight of that element

Answer 12

let me see what the atomic weight is

Answer 13

12.01

Answer 14

ok before we continue what do the lines in an element’s line spectrum represent?

Answer 15

ok 12 gram contains 6.023*10^23 atoms of carbon then
52 gram conatins = 6.023*10^23 *52 /12

Answer 16

electron transitions of that element it represents

Answer 17

is that the answer to What do the lines in an element’s line spectrum represent?

Answer 18

@chmvijay

Answer 19

electron transitions of that element it represents

Answer 20

ok got it thnx....oh yea what about the other question is this the correct answer "ok 12 gram contains 6.023*10^23 atoms of carbon then
52 gram conatins = 6.023*10^23 *52 /12"

Answer 21

@chmvijay are you still there

Answer 22

yaaa

Answer 23

electron transitions of that element it represents

Answer 24

no im talking about the original question
