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
A for growth and body repair
Molar mass H₂O = 18.015 g
number of moles:
mass of solute / molar mass
0.755 / 18.015
= 0.0419 moles
hope this helps !
