Question

Breathing air that contains 4.0 % by volume CO2 over time
causes rapid breathing, throbbing headache, and nausea,
among other symptoms. What is the concentration of CO2
in such air in terms of (a) mol percentage,

Accepted Answer

Hi everyone for this problem, we're being asked to calculate the mole percent of 02 in the air which is 6% by volume at 1 80 M and 30 degrees Celsius. So our goal here is to calculate mole percent. So let's just recall what is more percent. More percent is equal to our amount of solute and malls over our total amount of solute plus solvent. Also animals times 100%. So that is the definition of more percent. So we're being asked to calculate the mole percent of 02 in the air which is 6% by volume at 1 80 M and 30 degrees Celsius. So recall that for gasses at the same temperature and pressure, our volume percent is going to equal our mole percent. And so here they tell us that our volume is 6%. So that means our mole percent is also going to equal 6%. And this is our final answer. Okay, this is going to be our mole percent. That's the end of this problem. I hope this was helpful.
