From the density of ethanol given, the number of pounds of ethanol in the drum will be 46.099 pounds.
<h3>How to calculate density</h3>
Density of ethanol = 0.789/cm³
1 gallon = 3785.4ml
Volume of ethanol = 7 gallons = 7 × 3785.4ml = 26497.8ml
Mass of ethanol = Volume × Density.
= 26497.8 × 0.789
= 20906.764g
Since 1g = 0.002205 pounds, the mass of ethanol will be:
= 20906.764 × 0.002205
= 46.099 pounds.

Probably the answer will be 28.60 because it's a lower number
I am going to say D and C.
Butane undergoes combustion to produce carbon dioxide and water, expressed in the following reaction <span> C4H10 (g) + O2 (g) → 4CO2 (g) + 5H2O (g) . 1 mole of butane is to 4 moles of CO2. In this case, when 22.8 grams of butane or 0.393 moles of it, 69.18 grams of carbon dioxide is produced</span>
