Answer: 1. The volume of acetone is [tex]108cm^3[/tex]
2. The mass of acetone is 99 g.
Explanation:
Density is defined as the mass contained per unit volume.
[tex]Density=\frac{mass}{Volume}[/tex]
Given : Mass of acetone = 85.1 grams
Density of acetone = [tex]0.79g/cm^3[/tex]
Putting in the values we get:
[tex]0.79g/cm^3=\frac{85.1g}{Volume}[/tex]
[tex]Volume=108cm^3[/tex]
Thus the volume of acetone is [tex]108cm^3[/tex]
2. [tex]Density=\frac{mass}{Volume}[/tex]
Given : Mass of acetone = ?
Density of acetone = [tex]0.79g/cm^3=0.79g/ml[/tex] [tex]1cm^3=1ml[/tex]
Volume of acetone = [tex]125cm^3=125ml[/tex]
Putting in the values we get:
[tex]0.79g/ml=\frac{mass}{125ml}[/tex]
[tex]mass=99g[/tex]
Thus mass of acetone will be 99 g.
the volume of acetone = V= 107.72 cm³
the mass of acetone = m = 98.75 gr
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
[tex]\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}[/tex]
ρ = density
m = mass
v = volume
A common example is the water density of 1 gr/cm³
Acetone has a density of 0.79 g/cm³ at 20° C
[tex]\boxed{\bold{V=\frac{85.1\:gr}{0.79\:\frac{gr}{cm^3} }}}[/tex]
V= 107.72 cm³
[tex]\boxed{\bold{m=0.79\:\frac{gr}{cm^3}\times 125\:cm^3}}}[/tex]
m = 98.75 gr
