The mole
I truly am confused by this question. It gives no specific details.
Here it is. Calculate how long a chain of paper clips would be (in inches) if you had one mole of them. Can someone please answer this question, or at least guide me in the direction? |
||||
|
|
|
||||
|
Break it down into things you know.
How many atoms in a mole ? AND How long is an average paper clip ? Hint: The answer is a VERY large number. |
||||
|
|
|
||||
|
Yea I kind of figured that. BUT The big factor in this is that I just enrolled in chemistry.. Literally I don't know how to count atoms. How atoms are linked to moles or anything.. |
||||
|
|
|
||||
|
A Mole of atoms has a definition, what is it ?
Basically there are X atoms in a mole, what is X? Have a read of this: http://en.wikipedia.org/wiki/Mole_(unit) |
||||
|
|
|
||||
|
Okay.
6.02*10 to the 23? |
||||
|
|
|
||||
|
yep that's it.
The rest is easy. Isn't learning fun ;) |
||||
|
|
|
||||
|
:)
What about the rest? This is totally confusing |
||||
|
|
|
||||
|
Well you know what value a mole is, so now multiply by the length of a paperclip.
Then BINGO... |
||||
|
|
|
||||
|
Okay.one last thing.
I am truly asking this question How do you count the ruler marks. There's like 15marks and I thought a normal ruler was different. |
||||
|
|
|
||||
|
Now there you've got me.
Normally the small marks are To be honest the actual length isn't really that important. What they are looking for here is that you have researched what a mole is. After all paperclips come in tons of different sizes. |
||||
|
|
|
||||
|
Okay
Thank you sooo much! |
||||
|
|
|
||||
|
No worries.
Glad to help. |

One more thing.
Okay so you helped me find the 6.02*10 23 thingy. Now I have the measure of the paperclip. 1 4/16 Now how would I use the conversion chart to do that. The answer has to be in inches. Would it be a multiple step problem? |
||||
|
|
|
||||
|
Well the paper clip is X inches
and a Mole ( so it's simply Make sense ? |
||||
|
|
|
||||
|
Lol sort of.. but then again the fraction is going to get me. Would the answer be a mixed number or fraction or just a whole number? I'm so annoying |
||||
|
|
|
||||
|
Hey make it easy on yourself and say the paperclip is 2 inches ;)
Did they give you the paperclip to use or was it one you found in the house. |
||||
|
|
|
||||
|
One I found in the house.
|
||||
|
|
|
||||
|
Cool, so juts say it was 2 inches.
Makes thing easier all round. |
||||
|
|
|
||||
|
Okay. I think I have the answer.would the answer be 12.04*10 to the 23rd?
|
||||
|
|
|
||||
|
That's it.
Remember the answer isn't the whole problem. You need to show you whole working as I laid out in #14 above. That's how you get the full marks. |
