Question

Car exhaust contains 1.5% CO by volume. What is the [CO] in µg/m3 at 25°C amd 1 atm?

Expert Solution
Step 1: Solving

Car exhaust contains 1.5% CO by volume.

Taking basis =100 L

Volume of CO = 1.5 10L = 1.5 L =1.5 * 10-3 m3

Now at  25 degree C space equals 298 space K space comma a n d space 1 space a t m space equals space 101325 space P a

Now using the ideal gas law equation we find the number of moles of CO.

P V equals n R T 101325 space P a cross times space 1.5 cross times 10 to the power of negative 3 end exponent space m cubed space equals n space cross times 298 space K cross times 8.314 space fraction numerator P a. m cubed over denominator m o l space. space K end fraction n equals space 0.061345 space m o l e
