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

i think so it’s will be b yes i believe its

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
