Question

find the number of molecules and atoms of hydrogen in CH4

Answer 1

is it 6.022 * 10 ^23 molecules...

Answer 2

@Callisto

Answer 3

It should be...

Answer 4

then wat abt no of atom

Answer 5

is it 6.022 * 10^23

Answer 6

One mole of CO2 => one mole of C
So, it should be..

Answer 7

if the question is to find the number of molecules of hydrogen in CH4 then..

Answer 8

One mole of CH4 => 4 moles of H
=> no. of mole of CH4 x Avogadro's constant x 4

Answer 9

1 mole CH4 means 4 atoms of hydrogen...

Answer 10

hw it is 4 moles

Answer 11

1 CH4 molecule => 4 H atoms
1 mole of CH4 molecules => 4 mole of H atoms

Answer 12

*4 moles

Answer 13

ok then it is 4*6.022* 10 ^23 molecules!!

Answer 14

H atoms!!! not really molecules!!

Answer 15

then 6.022*10^23 molecules of h2

Answer 16

May I know what your exact question is?

Answer 17

find the number of molecules and atoms of hydrogen in CH4

Answer 18

Avogadro number of molecules

Answer 19

Number of molecules = Avogadro constant x number of mole of CH4
Number of atoms of H = Avogadro constant x number of mole of CH4 x 4
If I remember correctly

Answer 20

yup thxx

Answer 21

Mole is a number just like dozen. The number for dozen is 12 and the number for mole is 6.022 X 10^23. Now this would be for molecules in a mole of a molecular compound. If you were talking about atoms in a mole of an atomic element like gold, the answer would be 6.022 X 10^23 atoms. The only trick you run into is if you were asked how many atoms there are in a mole of CO2. In this case, there are still 6.022 X 10^23 molecules of CO2, but there are three atoms to each molecule of CO2 (One carbon and two oxygen atoms), therefore there would be 3(6.022 X 10^23) atoms in one mole of CO2.

Answer 22

@Yahoo! it think this will hlp u out.

Answer 23

@Ruchi. plzz read my question now i have made some corrections to it..

Answer 24

@Ruchi. Please don't copy and paste answer from other site!

Answer 25

@Callisto ohh really she want my hlp and i hav hlp her out it nt meanning ful to past it some where else or nt .it matter that i hav hlp her or nt or if i hav pasted it from some where else then why don't u tell the source to @Yahoo!

Answer 26

Sorry, I type all the above myself, I didn't copy it from somewhere else.
If I really need to tell a source, that is my teacher.

But in your case, you're probably copying from Yahoo! Answers: http://answers.yahoo.com/question/index?qid=20091124190426AA7qTEs
In that case, you'd better cite your reference.
