Question

Acetone is a common solvent and has a density of 0.7899 g/mL. What volume of acetone, in mL, has a mass of 28.7 g?

Answer 1

Density = 0.7899 g/mL

mass = 28.7 g

Volume = ?

therefore:

D = m / V

0.7899 =  28.7 / V

V = 28.7 / 0.7899

V  = 36.333 mL

Answer 2

The volume of acetone is = 36.33 mL

Further explanation

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 mass

The volume itself is a derivative of length with a standard unit of m³

Volume is the amount of how much space an object has  

The unit of density can be expressed in g / cm³ or kg / m³

Density formula:

$\large{\boxed{\bold{\rho~=~\frac{m}{V} }}}$

ρ = density

m = mass

v = volume

A common example is the water density of 1 gr / cm³

The mass itself is often equated with weight, even though it is different. Mass is the amount of matter in the matter while weight is related to the gravitational force

Known variable

mass of  28.7 g

a density of 0.7899 g/mL

Asked

volume in mL

Answer

mass is known to be 28.7 g,

then:

volume = mass / density

volume = $volume~=~\frac{28.7~g}{0.7899~g/mL}$

volume = 36.33 mL
