Answer:
Benzene is more denser.
Step-by-step explanation:
Given data:
Mass of ethanol = 3.9 g
Volume of ethanol = 5 mL
Volume of benzene = 5.0 mL
Mass of benzene = 4.4 g
which is denser = ?
Solution:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Density of ethanol:
d = m/v
d = 3.9 g/ 5 mL
d = 0.78 g/mL
Density of benzene:
d = m/v
d = 4.4 g/5.0 mL
d = 0.88 g/mL
So benzene is more denser.
