# Calculate CO concentration at high altitude

Question:

You are cooking in a tent at 17,000ft with outside air temp at -15F. The concentration of CO in the tent is 40ppm. Calculate the equivalent CO concentration in mg/m^3.

You are cooking in a tent at 17,000ft with outside air temp at -15F. The concentration of CO in the tent is 40ppm. Calculate the equivalent CO concentration in mg/m^3.

First, I converted 17000ft to atm and got 501.5atm, which seems very wrong.

Next, I converted -15F to 247.039K.

I applied the Ideal Gas Law, PV=nRT

I tried to solve for V.

p=501.5 atm

n(molecular weight CO)=28

R (should be a constant)=.082056

T=247.039

I come up with a ridiculous answer. It seems simple, but I can’t figure out where I’m going wrong.
