Question

What is the average mass of a single chlorine atom in grams?

Answer 1

@dpaInc here

Answer 2

im having lunch right now....cuz waiting for u took forever D:

Answer 3

How many atoms there are in a mole?

Answer 4

6.02x10^23

Answer 5

Cool, what's the molar mass of chlorine?

Answer 6

35.45

Answer 7

Cool, so what's the mass of 1 atom of chlorine?

Answer 8

take that multiply by that ?

Answer 9

\[\large 1 \text{ mole}=6.023*10^{23} \text{atoms}\]

Answer 10

\[\large 1 \text{ mole of chlorine}=34.45\text{g}\]

Answer 11

Transitivity property; \(\large 6.023*10^{23} \text{ atoms of chlorine}=34.45\text{g of chlorine}\)
Now you can do it.

Answer 12

You are looking for the mass of 1 atom.

Answer 13

34.45g/6.02x10^23 ??

Answer 14

yep

Answer 15

5.72x10^23

Answer 16

Should be \(\large 5.72*10^{-23}\)

Answer 17

You probably forgot to put \(6.023∗10^{23}\) in parentheses.

Answer 18

ohh so when you divide then you gotta put it in parenthesis? and when your multiply then don't need to ?

Answer 19

uh oh..."You are close. Check for rounding errors, and keep four sigificant figures in your answer."

Answer 20

why i put 5.723x10^-23 and it still wrong wtf o_0

Answer 21

@Blitzkrieg

Answer 22

Lemme see

Answer 23

@zepp hello?

Answer 24

Internet must stop lagging for nothing ;[

Answer 25

i got problem with this site yesterday too, otherwise this hw would've done :(

Answer 26

anyway, what to do with the 5.723x10^-23 ?

Answer 27

Try 5.73x10^-23

Answer 28

still wrong...it said check for rounding errors and it should be 4 sig fig.

Answer 29

omg chlorine is 35.45 not 34.45 zepp !! D:

Answer 30

zz :[

Answer 31

got 80% correct for that problem.... LOL after soo many fails

Answer 32

>.>

Answer 33

i posted 35.45 and you copied it wrong, and then i copied you and ....wrong lmao :)))

Answer 34

@Blitzkrieg WRONG

Answer 35

triple wrong... O__O

Answer 36

@Blitzkrieg bad!! Blitz!!

Answer 37

What is the mass (in grams) of 9.52 × 1024 molecules of methanol (CH3OH)?

Answer 38

Ahhh

Answer 39

Try 5.8858 * 10^-23 then?

Answer 40

i got it...already done...moving on!

Answer 41

What is the mass (in grams) of 9.52 × 1024 molecules of methanol (CH3OH)?

Answer 42

that's 10^24 btw

Answer 43

Oh cool

Answer 44

oh i know how to do this

Answer 45

Now it's conversion mole <-> atoms

Answer 46

is it a 3 steps problem?

Answer 47

first yu gotta convert from mole to mol and then from mol to grams right ?

Answer 48

506 g of CH3OH ?

Answer 49

Mole = mol o.o

Answer 50

mol is just a unit for mole, abbreviation.

Answer 51

oohhhh lmao =.=

Answer 52

well then i guess you just take that 9.52x10^24 x avogadro's number right ?

Answer 53

Divide

Answer 54

Looks like you have an enormous difficulty to distinguish when to divide or multiply :|

Answer 55

why is it divide? =.=

Answer 56

Number of Avagadro = # of atoms * (in) 1 mole of some substance.

Answer 57

\[\large 6.023*10^{23}=6.023*10^{23}*1\text{mol}\]

Answer 58

please do the calculation for me.. i wanna see how u do it

Answer 59

@zepp

Answer 60

omg it is 506 g of CH3OH !! i got it right D:

Answer 61

forget u zepp, i want Blitz back :D

Answer 62

Dad suddenly wants to disturb me.

Answer 63

:(

Answer 64

next problem:
How many grams of Cl are in 285 g of CaCl2?

Answer 65

We did many of this kind of question, you should be able to do them easily now :(

Answer 66

ok let me try, you check my answer ok? :D

Answer 67

alright

Answer 68

is it 140 g Cl?

Answer 69

Put it in the box and see if you got it right or not, be self-confident :)

Answer 70

D: !

Answer 71

cuz i already got 4 wrong for that problem so...self confident is gone hahaha
