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
