Question

Question 2 1 pts If an automobile travels 225 miles with a gas mileage of 20.5mi/gal, how many kg of CO2 are produced? Assume the gasoline is composed of octane, C3H18, whose density is 0.69 g/mL. Question 3 1 pts 40 ml sample of 6M Rr are mixed. The

how to solve

Answer 1

Given Distance = 225 miles mileage = 2015 milgel gasoline needed a Distance mileage s miles miles a 225 mi 20.5 milgal gasoline needed = 10.975 gal I gallon = 3.785 l 10.975 gol = (10.975) Cigal) - = (10.975) (3.785 l) = 1410 54 e gasoline needed = 41.546. Density = 0.69 glme О. К Ime=103 mass = volumex density mass of gesoline = (41.544) (0.69 kg ) Mass of gasdine = 28.66 kq. Given gasdine is composed of cgtig Mags of cotto = 28.66 ke Molar mag of Ca Hip = 114.23 kg / kmd Moles = mass Molar mass = 28.66 kg 114.23 kg / kimos Moles of Co. His = 0.2508 kmal

Reaction: 226 H 18 int 2500 16 gt 18, H₂0 W 16 mol 16 kmol 7 Stoichiometic a mol coefficients akimol I I 2 kmol & His l kmol Celtig 0.2508 kmol produces 16 kmol of co produces 8 kmol of co₂ Caltig produces 8x0.2508 = 2.0064 kmolt Moles of co, produced = 2.0064 kmol. Molar mass of CO2 = 44,01kg /kmol Mass of co = (210864 kma) (44.01 kg/ = 88.3 kg ) Mass of co2 Produced = 88.3 kg.
