Homework Statement
The air near a water heater in the basement of an old home is measured for carbon monoxide (CO) and found to contain 0.1% by volume CO at 22*C and 1 atm. Express the CO concentration in the basement in micro-gram/m^3 .
Homework Equations
PV=nRT
P = absolute pressure (atm); V = volume (m3 ); n = mass (mole); R = ideal gas constant = 0.082056 L atm K−1 mol−1 ; and T = absolute temperature (K).
The Attempt at a Solution
The answer said that 0.1% = 10^−3 ppm = 10^3 L CO/ 10^6 L air. But in the book it also has equation to express that {% by volume} x 10000 =ppm. I don't know which one is correct and how to use them.
Beside, after I have calculated the gram of CO, how to relate it with the micro-gram/m^3 ?
thank you.
