Answer:
Benzene is denser than ethanol.
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.
Answer:
Benzene
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.
