A compact car gets 37.5 milon on the highay. If gasoline contains 84.2$\%$ carbon by mass and has adensity of 0.8205 $\mathrm{g} / \mathrm{mL}$ , determine the mass of carbon dioxide produced during a $500-\mathrm{mile}$ trip $(3.785 \text { liters per }$ gallon).

this question says that a compact car gets 37.5 miles per gallon on the highway that it says if gasoline contains 84.2% carbon by mass and has a density of 0.8205 grams per mil determined the mass of carbon dioxide produced during a 500 mile trip. I think it is the conversion between leaders and gallons. Let's begin with a 500 mile trip. 1st 1 to figure out how many gallons is it gonna take to go 500 miles? It tells us that in one gallon one gallon it gets 37 25 miles and that'll tell us how many gallons of gas we need. But our conversion for density is in units of middle leaders. We want to convert from 500 miles. I'm sorry from Galan's to that many leaders gives the conversion that one gallon is 3.75 0.75 liters. Next, we're gonna convert to the density, but this could be a two step process because it tells us the mass of carbon in gasoline has in gasoline is 84.2% and the density of gasoline itself has 0.8205 so off that 0.8205 grams, only 84% of it is carbon. The rest would soon as hydrogen oxygen, so the density of carbon itself would be 0.8 for two times intensity of gasoline itself. 28 two 05 grams. This is grams per mil leader, but our unit for converting two gallons and leaders some of the right one. Metal leader is 10.0 zero one Leaders, which is one no leader. Then, finally, this is Graham's of carpet need to convert from grams of carbon, two grams of carbon dioxide. So for every 12 approximately 12 grams of carbon, there would be 44 grams carbon dioxide. Great if we were to put this on when we can see their units. Cancel Miles Callens eaters. Mrs Graham's Carbon Love with grams of Co two. You get about 128,000 grams, or about 128 kilograms of CO.
