Standard temperature and pressure?
The normal respiratory rate for human being is 15.0 breaths per minute. the average volume of air for each breath is 505 cm^3 at 20.0C and 9.95 x 10^4 Pa. what volume of air at STP that an individual breaths in one day? give answer in cubic meters. 1.00 atm = 101.325k Pa.
need help on the steps don't get it... thank you.
T = 0C
P = 1.00 atm

You will need to answer three parts.
1) How many breaths does a person breath in a 24 hour period, if they breath 15 breaths per minute?
2) Then you can convert this to volume by multiplying it by 505 cm^3.
3) Then you will need to convert that volume to STP by using the ratio of (P1 * V1)/T1 = (P2 * V2)/T2 Plug in ALL variables using the values for STP as P2 and T2. (remember to convert 99.5k Pa to atm)
