Barbara Norman · Answer 1

Mass of benzene is: 149.3 g

Explanation:

Let's use density to calculate mass.

Density = Mass / Volume

Mass = Density. volume

Be careful, because density is in g/mL and the volume is in L. So let's convert the L to mL: 0.170 L. 1000 mL / 1L = 170 mL

0.8787 g/mL. 170 mL = Mass of benzene

Mass of benzene is: 149.3 g
