1. I have been asked to to calculatethe density of methane gas from the following information:
Mass of methane held within the container=0.000734kg,
internal volume of container=0.011 m3

I came up with 0.00734
----------=0.667272727
0.011

Can anyone help me present an altrenative version of the answer that you think would very well demonstrate the use of mathematicle skills. [/i]  2. ### Related Discussions:

Your approach (division) is correct. However you should check to see that the numbers you used are correct (hint - they are not!).  4. I think what you are getting at is that you want an answer that shows you can use good math skills. What you need to know and i think you know this is that density is mass per unit volume so what you could do to show your math skills is convert to different units for each of those. Instead of kg you could convert to grams, milligrams, lbs, any measure of mass. Instead of m^3 you could convert to cm^3 which is a mL, or any other volume units. That is about the only way you can do it to show use of different math skills.  5. Originally Posted by HarryPotter

Ya......... what ever he (harry) said.   6. You could show your understanding of significant figures by rounding the result appropriately.

You should also state the units of the result of your calculation.  7. Scientific Notation for the numbers  8. I found that connector you were looking for
Cindy, is this the thing you were looking for?
