The estimated average concentration of carbon monoxide in air in the United States in 1991 was 6.0 ppm. Calculate the number of CO molecules in 1.0 L of this air at a pressure of 601 torr and a temperature of 20.°C.
The Attempt at a SolutionI tried this and using pv=nrt
pressure was converted to torr
volume was 1
r was taken as 8.31
temp was converted into K
n was solved for, and muktiplied by avagadro's number
Am i missing something? am i supposed to include the ppm?
i am so confused.
