Density Calculation: Understanding the Concept of Density
What is meant by the term density?
The term density is defined as the measurement of how tightly a material is packed together. It is also defined as the mass per unit volume. Density Symbol is D or ρ.
How is density represented in formula?
Answer:
The term density is defined as the measurement of how tightly a material is packed together. It is also defined as the mass per unit volume. Density Symbol is D or ρ. Density is represented by the Formula as follows: ρ = m/V, where ρ is the density, m is the mass of the object and V is the volume of the object.
Density Calculation: Density can be calculated by dividing the mass of an object by its volume. In the given scenario, the mass of the flask and stopper are 110.525g, and the total mass with gasoline added is 146.770g. The volume of the gasoline sample is 50.0ml.
Given: Mass (M1) = 110.525g, Mass (M2) = 146.770g, Volume V = 50.0ml
Density Calculation: Subtracting the initial mass from the final mass gives the mass of the gasoline alone: 146.770g - 110.525g = 36.245g
Calculate Density: Density is calculated by dividing the mass by the volume. Density = Mass/Volume = 36.245g / 50.0ml = 0.725g/mL
Conclusion: Therefore, the density of gasoline in the given scenario is 0.725g/mL, which represents how tightly packed the gasoline molecules are in the flask.
