Answer 1

n Distance travelled in one year = 12,000 miles Distance travelled Den gallon = 48.0 miles gallon. (In 1 year) (P) & Gasoline used in 1 year= Distance travelled Distance travelled per = 12000 miles - 666.67 gallong gal 18.0 miles gallon = ~ 6.67 X 102 gallons (③ Volume of Gasoline used in 1 Year = 666.67 gallory Also I gallon = 3785.412 ml 7 3785.412 ml = 1 Igallon % Volume of Grasoline used (in ml) = 666.67 gallonxx 3785.412mL 1 gallon - = 259 3 6 20.52 ml As Density = 0.103 gime - Mass of Gasoline used in 1 Year = Volume & Density -2523620.62 mL X 0.703g me __= 1774105.39 ã 7.71x torg : (C) No of moles Gasoline (C&lig) = Mass = 1774105.39 __ Malay May 114.23g| mal =15530.9927 mal - 1 :1 .
