AI Thread Summary
The discussion revolves around calculating the mass of carbon monoxide (CO) in 1 liter of exhaust gas, which contains 8% CO by volume. Participants clarify that SLC likely refers to Standard Laboratory Conditions or Normal Temperature and Pressure (NTP), with the latter having a molar volume of 24.4 L/mol at 25°C and 1 atm. To find the mass of CO, one must first determine the volume of CO in 1L of exhaust gas, which is 0.08L. This volume can be converted to moles using the molar volume, and then the number of moles can be converted to mass using the molar mass of CO from the Periodic Table. The conversation highlights the importance of understanding the conditions under which the molar volume is defined, as well as the steps needed to transition from volume to mass in gas calculations.

The exhaust gas from a car is tested and found to contain 8% by volume of carbon monoxide. If the molar volume of CO at SLC = 24.4 L/mol, what is the mass of carbon monoxide in 1L of exhaust gas?

I'm very new to these calculations and am unsure how to approach it.

What is SLC? Anyways, you want to know the mass of carbon monoxide in 1L of exhaust gas. You know the volume in 1L of exhaust gas, that's 8% of 1L, or 0.08L. Now, what can we use to go from volume to mass? Well, I think you can see how to get from volume to number of moles (look at what's given in the question). And you know how to go from number of moles to mass (look at your Periodic Table).
 
by SLC do u mean STP(Standard Temp Pressure)?
 
Yer probably...
Might be a type in the question.
 
STP is 0C (273K), 1 atm. The molar volume at STP is 22.4 L, not 24.4 L

NTP is 25C (298K), 1 atm. The molar volume at NTP (Normal temp. & press.) is 24.4L

Never heard of SLC before - other than as an abbreviation for Salt Lake City.
