A Nail Polish Bottle Contains 8 Ml Of Liquid. Calculate The Total Mass Of The Nail Polish And The Bottle, If The Bottle Itself Weighs 55 G.
Introduction
In this discussion, we will explore the concept of density and how it can be used to calculate the mass of a substance. We will use the given information about a nail polish bottle containing 8 ml of liquid and the weight of the bottle itself to determine the total mass of the nail polish and the bottle.
Understanding Density
Density is a fundamental concept in chemistry that describes the mass of a substance per unit volume. It is typically denoted by the symbol ρ (rho) and is measured in units of mass per unit volume, such as grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).
The formula for density is:
ρ = m / V
where ρ is the density, m is the mass, and V is the volume.
Given Information
We are given that the nail polish bottle contains 8 ml of liquid and that the bottle itself weighs 55 g. We need to calculate the total mass of the nail polish and the bottle.
Calculating the Mass of the Nail Polish
To calculate the mass of the nail polish, we need to know its density. However, the density of nail polish is not provided. We can assume a typical density for nail polish, which is around 0.9-1.2 g/mL. For the purpose of this calculation, we will use a density of 1 g/mL.
Using the formula for density, we can calculate the mass of the nail polish as follows:
m = ρ * V
where m is the mass, ρ is the density, and V is the volume.
Plugging in the values, we get:
m = 1 g/mL * 8 mL m = 8 g
Calculating the Total Mass of the Nail Polish and the Bottle
Now that we have calculated the mass of the nail polish, we can add it to the weight of the bottle to determine the total mass of the nail polish and the bottle.
Total mass = mass of nail polish + weight of bottle Total mass = 8 g + 55 g Total mass = 63 g
Conclusion
In this discussion, we used the concept of density to calculate the mass of a nail polish bottle containing 8 ml of liquid. We assumed a typical density for nail polish and used the formula for density to calculate the mass of the nail polish. We then added the mass of the nail polish to the weight of the bottle to determine the total mass of the nail polish and the bottle.
Calculating the Mass of the Nail Polish with Different Densities
To further explore the concept of density, let's calculate the mass of the nail polish using different densities.
Density of 0.9 g/mL
m = ρ * V m = 0.9 g/mL * 8 mL m = 7.2 g
Total mass = mass of nail polish + weight of bottle Total mass = 7.2 g + 55 g Total mass = 62.2 g
Density of 1.2 g/mL
m = ρ * V m = 1.2 g/mL * 8 mL m = 9.6 g
Total mass = mass of nail polish + weight of bottle Total mass = 9.6 g + 55 g Total mass = 64.6 g
Conclusion
In this discussion, we calculated the mass of a nail polish bottle containing 8 ml of liquid using different densities. We used the formula for density to calculate the mass of the nail polish and added it to the weight of the bottle to determine the total mass of the nail polish and the bottle.
