The volume of acetone is $\boxed{0.0444{\text{ c}}{{\text{m}}^3}}$ .

Further Explanation:

Properties of any substance can either be intensive or extensive.

Intensive properties are the ones that depend on the nature of the substance, not on the size of the system. These properties remain the same even if the system is further divided into a number of subsystems. Examples of intensive properties are temperature, refractive index, molarity, concentration, pressure, and density.

Extensive properties are those that depend on the amount of the substance. These properties are additive in nature if a single system is divided into many subsystems. Examples of extensive properties are mass, enthalpy, volume, energy, size, weight, and length.

The ratio of mass to the volume of the substance is known as density. It is usually denoted by ${{\rho }}$ . The density of a substance is calculated by the following formula:

${\text{Density of substance}} = \dfrac{{{\text{Mass of substance}}}}{{{\text{Volume of substance}}}}$ …… (1)

Rearrange equation (1) to calculate the volume of the substance.

${\text{Volume of substance}} = \dfrac{{{\text{Mass of substance}}}}{{{\text{Density of substance}}}}$ …… (2)

The mass of the substance is to be converted into g. The conversion factor for this is,

$1{\text{ mg}} = {\text{1}}{{\text{0}}^{ - 3}}{\text{ g}}$

So the mass of the substance is calculated as follows:

$\begin{aligned}{\text{Mass of substance}}&= \left( {{\text{35 mg}}} \right)\left( {\frac{{{{10}^{ - 3}}{\text{ g}}}}{{1{\text{ mg}}}}} \right)\\&= 0.035{\text{ g}}\\\end{aligned}$

Substitute 0.035 g for the mass of the substance and $0.788{\text{ g/c}}{{\text{m}}^3}$ for density of substance in equation (2) to calculate the volume of acetone.

$\begin{aligned}{\text{Volume of acetone}}&= \frac{{0.035{\text{ g}}}}{{0.788{\text{ g/c}}{{\text{m}}^3}}}\\&=0.0444{\text{ c}}{{\text{m}}^3}\\\end{aligned}$

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or
