Answer:

Density,
$d=2.09\ g/cm^3$

Step-by-step explanation:

Given that,

Mass of a flask is 450 g

Volume of benzene added to the flask is 145 mL or 145 cm³

The weight of the flask and benzene is found to be 754 g.

We need to find the density of the benzene.

Weight of benzene added = total weight of flask and benzene-mass of flask

m = 754 g - 450 g

m = 304 g

Density = mass/volume

So,

$d=(304\ g)/(145\ cm^3)\\\\d=2.09\ g/cm^3$

So, the density of the benzene is
$2.09\ g/cm^3$ .
