5.The normal respiratory rate for a human being is 15.0 breaths per minute. The average volume of air for each breath is 505 cm ex3 at 20.0*C and 9.95 x 10 ex4 Pa. What is the volume of air at STP that an individual breathes in one day? Give your answer in cubic meters.

I'm pretty sure the formula is going to be in your textbook, you just need to do the math. You need to use the ideal gas law to compensate to STP.
You also need to make sure each of your questions has a different subject line. That's why the thing comes up with the "similar questions" thingy... to keep you from doing what you did. Do not just ask for the answer - post your work and ask if you did it right.

You can adjust the 505 cm^3 figure to STP as follows: V = 505 x 273/293 x 995/1013.25 . (Why?) Multiply the result by 4 x 60 x 24 and convert to m^3.

breaths/min x min/day x volume/breath= volume/day (in cc). Divide that by 10^6 to go to m^3. Now adjust for STP conditions from the given conditions.
