A science teacher gives a student four beakers, each with a different liquid inside. The table provided shows the volume of each liquid. Students will need to measure the mass of each liquid in order to calculate the density. When the student mixes all four liquids into one beaker, each liquid separates into a different layer. Using the volume and mass, students will calculate the density of each liquid and list them in order from least dense to most dense. What is the outcome variable (dependent variable) in this experiment? Please Hurry i have until midnight of today! Thank youu so much

The dependent variable in this experiment is the mass of each liquid.

Density is the ratio of mass to volume of a substance. In this experiment, since the volume of each liquid is given, to get density, mass of each quantity must be known which is the outcome.

Density also depend on the mass of a substance and density can easily be identified by mass if all the substance in question have the same volume.

In this experiment, all the liquid have the same volume. Since the student want to list them in order from the least dense to the most dense, how dense the liquid are will be a function of the differences in liquid mass.

The least dense liquid will float. That is, will be at the top most of the container. While the most dense will be at the bottom of the container.

Therefore, the dependent variable in this experiment is the mass of each liquid

The concept of density allows finding the density and ordering the liquids from lowest to highest they are:

  •  dishwashing liquid < vegetable oil < water < corn syrup
  • The dependent variable of the experiment is the mass of each body.

Density is the relationship between mas and volume, it is one of the most used relationships in liquids,

            [tex]\rho = \frac{m}{V}[/tex]

where ρ is the density, m the mass and V the volume

Systems of units are systems of measurements where fundamental units are defined by convention and are used to be able to exchange measurements with precision and accuracy. The most widely used system today is the international measurement system (SI), let's reduce the magnitudes to this system

We use that one milliliter of water is equal to 1 cm³ of water

                    V = 10 cm³ ( [tex]\frac{1m}{100 cm}[/tex] )² = 10 10⁻⁶ m³

In this exercise they give that the volume for all the liquids are equal, the mass is a measure in a triple beam balance whose appreciation is 0.1 g = 0.1 10⁻³ kg, in the following table we find the reading of the mass for each substance

Material         Mass (10⁻³ kg)      Density (kg / m³)

Dish soap           9.1                           910

Vegetable oil     9.5                          950

Water                  9.97                        997

Corn syrup        14.2                         1420

We calculate the density

Liquid dishwasher

                       [tex]\rho = \frac{9.1 \ 10^{-3} }{10 \ 10^{-6}}[/tex]

                       ρ = 910 kg / m³

The other values ​​are calculated in the same way and it is in the last column of the table

The independent variable in an experiment is the one that the researcher controls, in this case the volume of each sample and the dependent variable is the one that the researcher measures in this case the mass of each material.

In conclusion, using the concept of density, we can order the liquids by their density from lowest to highest they are:

  • Dishwashing liquid < Vegetable oil < Water < Corn syrup
  • The dependent variable of the experiment is the mass of each body.
