The diesel tank on my tractor has a capacity of 11.0 gallons

August 23, 2020/in Feeds /by admin

The diesel tank on my tractor has a capacity of 11.0 gallons. Assume the density of petroleum diesel is 0.832 kg/L.
(1) When my tank is full, what is the mass of fuel in pounds? Potentially useful information: 1 gal = 3.79 L; 1 lb = 453.59 g.

(2) Diesel fuel is actually made of various hydrocarbon compounds that have carbon chains ranging from 8 to 21 carbon atoms. For the sake of simplicity, assume the average formula is C12H23 (the 12 and 23 are subscripts). If we use this as the formula for diesel fuel, how many moles of diesel fuel molecules are in a full tank?

All work must be shown, labeled, and explained in detail to receive credit. Note that superscripts (X2) can be written as X^2 and subscripts (X2) can be written as X_2 if it saves you time. Be careful to account for significant figures in your final answer
