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.

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.
1. Under certain conditions, the density of dry air is 1.205 g/L. What is the mass of air in a room that is 4.65 meters wide by 5.25 meters long by 7.50 meters high?
2. A piece of silver metal weighing 194.3 grams is placed in a graduated cylinder containing 242.0 mL of water. The volume of water now reads 260.5 mL. From these data, calculate the density of silver.
If a monolayer of stearic acid has a mass of 2.5*10^-5 g and occupies a surface area of 82 cm^2, what is the height of the monolayer, in cm? The density of stearic acid is 0.839 g/cm^3.
A student determined in a set of four experiments that the density of magnesium metal was 1.66 g/ml,1.65 g/ml, 1.67 g/ml, 1.67 g/ml. The accepted value for its density is 1.72 g/ml. What can you concludeabout the precision and accuracy of the student’s data?
