Assume that the gasoline is composed of octane, CHs(!), whose density is 0.69 g/ml Express your answer using two significant figures ke Submit PartB Repeat the calulation for a truck that has a gas mikage ot 6 mi/gal migat Express your answer using one significant figure kg Provide Feedback

Explanation / Answer

part A)

distance = 225 mi

milage = 21.0 mi / gal

volume of gas = 225 / 21 = 10.71 gal

                         = 40557.98 ml

mass of gas = 40557.98 x 0.69 = 27985 g

moles of gas = 244.988 mol

2 mol gas   ------------> 16 mol CO2

244.988 mol   --------> ??

moles of CO2 = 244.988 x 16 / 2 = 1959.9 mol

mass of CO2 = 86 kg

part B)

volume = 37.5 gal

mass of gas = 97947.50 g

moles of gas = 857.47 mol

moles of CO2 = 6859.8 mol

mass of CO2 = 3 x 10^2 kg
