The volume of benzene in the drum is "3859 mL", or "3.859 L".

Explanation:

In order to determine the volume, we need to calculate the mass of benzene and convert it to grams because the density is in grams/milliliter (g/mL). Then divide the mass by the density to calculate the volume of the benzene.

Calculate the mass of benzene in the drum.

"Mass of empty drum=5.035 kg"
"Mass of empty drum filled with benzene=8.418 kg"

"Mass of benzene"="8.418 kg"-"5.035 kg"="3.383 kg"

Convert mass of benzene to grams.

"1 kg= 1000g"

3.383 color(red)cancel(color(black)("kg"))xx(1000 "g")/(1 color(red)cancel(color(black)("kg")))="3383 g"

Calculate the volume of the benzene.

"density"="mass"/"volume"

"volume"="mass"/"density"

"volume"=(3383color(red)cancel(color(black)("g")))/(0.8766color(red)cancel(color(black)("g"))/"mL")="3859 mL"="3.859 L" rounded to four significant figures
