Answer:
5,747.82 pounds of would your car release in a year if it was driven 170 miles per week.
Explanation:
Mileage of the car = 27.5 miles/gal
Distance driven by car in week = 170 miles
Distance driven by car in a day=
Volume of gasoline used in a day : V
Density of the gasoline = d=
Mass of the gasoline used in a day = m
Moles of gasoline ( isooctane):
=
According to reaction , 2 moles of isooctane gives 16 moles of carbon dioxide gas.Then 20.292 mole isooctane will give :
of carbon dioxide gas
Mass of 162.340 moles of carbon dioxide gas :
162.340 mol × 44 g/mol = 7,142.91 g
Mass of carbon dioxide gas produced in a day = 7,142.91 g
1 year = 365 days
Mass of carbon dioxide gas produced in a 365 days:
= 365 × 7,142.91 g = 2,607,163.494 g
1 pound = 453.592 g
5,747.82 pounds of would your car release in a year if it was driven 170 miles per week.
