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

The mass of the ethanol is 322.6 pounds

Explanation:

Density is defined as the mass contained per unit volume.

Given : Mass of ethanol = ?

Density of ethanol=

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

Putting in the values we get:

        (1g=0.00220462pound)

Thus the mass of the ethanol is 322.6 pounds

not clear

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
