Question

Ethanol is a common laboratory solvent and has a density of 0.789 g/mL. What is the mass, in pounds, of 49.0 gal of ethanol

Answer 1

Answer: The mass of the ethanol is 322.6 pounds

Step-by-step explanation:

Density is defined as the mass contained per unit volume.

`Density=(mass)/(Volume)`

Given : Mass of ethanol = ?

Density of ethanol=
`0.789g/ml`

Volume of ethanol = 49.0 gal = 185485 ml ( 1gal=3785ml)

Putting in the values we get:

`0.789g/cm^3=(xg)/(185485ml)`

`x=146347g=322.6pound` (1g=0.00220462pound)

Thus the mass of the ethanol is 322.6 pounds
