In summary, to find the mass of carbon monoxide in 1L of exhaust gas, we can use the given information that the exhaust gas contains 8% by volume of CO. Using the molar volume of CO at NTP, which is 24.4 L/mol, we can convert the volume of CO in 1L of exhaust gas to moles. Then, using the molar mass of CO from the Periodic Table, we can convert moles to mass and determine the mass of CO in 1L of exhaust gas. It is important to note that SLC is not a commonly used abbreviation and it is likely that the question meant to use STP (Standard Temperature and Pressure) or NTP (Normal

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.
 

What is the formula for calculating gas mass/volume?

The formula for calculating gas mass/volume is M = PV/RT, where M is the mass of the gas, P is the pressure, V is the volume, R is the gas constant, and T is the temperature.

How do you convert gas volume from one unit to another?

To convert gas volume from one unit to another, you can use the ideal gas law, PV = nRT. Rearrange the equation to solve for V, and then plug in the given values for the pressure, moles, gas constant, and temperature. This will give you the volume in the desired unit.

What is the difference between mass and volume?

Mass is the measure of the amount of matter in an object, while volume is the measure of the amount of space an object occupies. Mass is typically measured in grams or kilograms, while volume is measured in liters or cubic meters.

How does gas volume change with temperature and pressure?

According to Charles' Law, the volume of a gas is directly proportional to its temperature, while according to Boyle's Law, the volume of a gas is inversely proportional to its pressure. This means that as temperature increases, gas volume increases, and as pressure increases, gas volume decreases.

What are some common units for measuring gas volume?

Some common units for measuring gas volume include liters (L), cubic meters (m^3), and cubic feet (ft^3). Other units such as milliliters (mL) and gallons (gal) may also be used, depending on the specific application.
