Question

If the density of coconut oil is $ 0.925{\text{ g/c}}{{\text{m}}^3} $ ? How much does $ 4.25 $ mL weigh in grams?

Answer 1

Hint: The formula relating density to volume and mass is to be used in this question. The units used in this question should be in one form, that is if in SI unit then SI or if in CGS unit then all the quantities should be measured according to the CGS unit system. We shall substitute the values in the formula given below.
Density = Mass / Volume

Complete Step by step solution
Density is equal to mass per volume. Density is also known as volumetric mass density or specific mass. Density of any material varies with temperature and pressure. The most often symbol used for density is rho.
More dense material will have less volume than an object of equal mass made from some less dense substance. Density has the same numerical value as its mass concentration for a pure substance. Temperature and pressure affect the density of a substance. As the pressure on an object or a substance increases, the volume of the object decreases and hence its density increases. As the temperature increases, the volume of the material of the substance increases and its density decreases.
To compare density across different systems of units, it is sometimes replaced by the dimensionless quantity relative density or specific gravity. It is the ratio of the density of the material to that of a standard material which is usually water. Specific volume is the reciprocal of the density of a substance. It is sometimes used in thermodynamics. Density of coconut oil is $ 0.925{\text{ g/c}}{{\text{m}}^3} $ .
Volume of the coconut oil is $ 4.25 $ mL or $ 4.25{\text{ c}}{{\text{m}}^3} $ .
Here, the mass of the coconut oil can be calculated as follows,
Mass = Density x Volume = $ 0.925 \times 4.25 $ = $ 3.93 $
 Therefore, the mass of coconut oil is $ 3.93 $ g.

Note
1 $ c{m^3} $ is equal to 1 mL. Coconut oil is a naturally occurring oil that is a natural oil. Coconut oil is a plant oil. It is derived from the kernels and milk of coconut palm and fruit. It can be used as a cooking oil as well as hair oil.
