Answer: depending on the method, 138-139 (imperial) gallons, or 626 L
Explanation:
The wt of water is 4924-3547 lb = 1377 lb = 1377/2.2 kg = 626 kg = 626 L
1gallon = 4.5 L (it does where I come from and who still measures things in imperial anyway?) so I guess that is 139 gallons
or alternatively, I recall from distant childhood, “a pint of water weighs a pound and a quarter” which means 1 gallon = 10 lb, so 1377 lb = ~138 gallons
The purpose of washing the organic product that contains water with anhydrous calcium chloride is to remove water from the organic product, thereby, increasing its purity. Calcium chloride is known to be one of the most effective drying agents together with sodium sulfate and magnesium sulfate. It is especially used for hydrocarbons. It is an inorganic salt that readily takes up the water from the organic product.
I would say fall/ autumn in South America because they are in opposite hemispheres.
I'm pretty sure it's organic chemistry.
C2H2 is the right answer I believe
