Best ResponseYou've already chosen the best response.0\[2.8gal(gasoline)*\frac{3.79L}{1gal}*\frac{1000mL}{1L}=10612mL(gas)\]\[D=\frac{m}{V} \rightarrow m=DV\]\[m=(0.66g*mL^{1})(10612mL)=7003.92g(gas)\]\[7003.92g(gas)*\frac{11,500kcal}{1.0g(gas)}=80,545,080kcal\]We need to report it to 2SFs...\[8.1*10^7kcal\]
