A sample of ethanol has a volume of 7.5 mL and a mass of 5.85 g. A sample of benzene also has a volume of 7.5 ml,

but has a mass of 6.60 g. Which liquid is denser

Answer:

Benzene

Step-by-step explanation:

You need to calculate the densities for each compound.

EtOH = 5.85/7.5 = 0.78 g/mL

Benzene = 6.60/7.5 = 0.88 g/mL

0.88 > 0.78, thus benzene is denser than ethanol.

Answer:

Benzene is denser than ethanol.

Step-by-step explanation:

Given data:

Volume of ethanol = 7.5 mL

Mass of ethanol = 5.85 g

Volume of benzene = 7.5 mL

Mass of benzene = 6.60 g

Which is denser = ?

Solution:

First of all we will calculate the density of both substances.

Density of ethanol:

d = m/v

d = 5.85 g/ 7.5 mL

d = 0.78 g/mL

Density of benzene:

d = m/v

d = 6.60 g/ 7.5 mL

d = 0.88 g/mL

The density of benzene is higher thus it is denser than ethanol.
