A 55.0 gallon drum weighs 75.0 lb when empty. What will be the total mass when filled with ethyl alcohol? ( Density = 0.789 g/mL , 1 gallon = 3.78 L, 1lb = 454 g.
1 answer:
Answer:
mass drum (filled) = 198.083 Kg ( 436.306 Lb )
Explanation:
⇒ mass drum = 75.0 Lb * ( 454 g / Lb) = 34050 g ( 34.05 Kg )
⇒ volume drum = 55.0 gal * ( 3.78 L/gal ) = 207.9 L
⇒ density CH3CH2OH = 0.789 Kg/L
⇒ mass drum (filled) = 34.050 Kg + ( 207.9 L * 0.789 Kg/L )
⇒ mass drum (filled) = 34.050 Kg + 164.03 Kg
⇒ mass drum (filled) = 198.0831 Kg
