Question

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?

Answer #1

The density of ethanol = 0.789g/cm^3

1gallon = 3785.4ml

The volume of ethanol = 5gallons = 5*3785.4 = 18927ml

mass of ethanol = volume * density

= 18927*0.789 = 14933.4g

1g = 0.002205pounds

mass of ethnol = 14933.4g = 14933.4*0.002205 = 32.93pounds of ethanol >>>>>answer

Ethanol (C2H5OH) boils at 78∘C. Its density is 0.789 g/mL. The
enthalpy of vaporization is 38.56 kJ/mol. The specific heat of
liquid ethanol is 2.3 J/g−K.
1. How much heat is required to convert 25.0 g of ethanol at 30
∘C to the vapor phase at 78 ∘C?
2. Place the following substances in order of decreasing
volatility: CH4, CBr4, CH2Cl2, CH3Cl, CHBr3, and CH2Br2. Rank from
most volatile to least volatile. To rank items as equivalent,
overlap them.
