The crucible given to a student is made of pure platinum, is to be proved based on measurements and given density of platinum. Concept introduction: Dimensional analysis is used to set up and solve a unit conversion problem using conversion factors. The conversion factor is a fraction obtained from a relationship between the units. It is written as a ratio and can be inverted to give two conversion factors for every relationship. The appropriate conversion factor for any equality is selected in such a way so that it results in the proper unit cancellation. One milliliter is equivalent to one cubic centimeter. Conversion factor is as: 1 mL 1 cm 3 The relationship between density and volume of a substance can be expressed as: ρ = m V Here, ρ is the density of the substance, m is the mass of substance, and v is the volume.

Interpretation:

The crucible given to a student is made of pure platinum, is to be proved based on measurements and given density of platinum.

Concept introduction:

Dimensional analysis is used to set up and solve a unit conversion problem using conversion factors.

The conversion factor is a fraction obtained from a relationship between the units. It is written as a ratio and can be inverted to give two conversion factors for every relationship.

The appropriate conversion factor for any equality is selected in such a way so that it results in the proper unit cancellation.

One milliliter is equivalent to one cubic centimeter. Conversion factor is as:

1 mL1 cm3

The relationship between density and volume of a substance can be expressed as:

ρ=mV

Here, ρ is the density of the substance, m is the mass of substance, and v is the volume.
