Ethanol (the drinking alcohol) C2H5OH, has a density of 0.789 g/cm3. How many pounds of ethanol would be in a drum containing 5.0 gallons of ethanol?

Expert Solution

Density of ethanol = 0.789 g/ mL

Volume of tank = 5.0 gallons

Or, volume of tank = 5.0 x (3785.41 mL) ; [1 gallon = 3785.41 mL]

= 18927.10 mL

# Mass of ethanol in tank = Volume x Density

= 18927.10 mL x (0.789 g/ mL)

= 14933.4819 g ; [1 g = 14933.4819 lb]

= 14933.4819 x (0.00220462 lb)

= 32.923 lb

Hence, amount of ethanol in tank = 32.923 lb

The density of a 10 kg cube of silver is 10.5 g/cm3. What would the density of a 5 kg cube of silver be? I thought the answer would be 5.25 g/cm^3 because m1/m2=p1/p2 so 10kg/5kg=10.5 g/cm^3/ x and you solve for x. But this is coming up as wrong and I don't know why, do i need to convert the kg to g???
