Tap Water Lab

Density describes a substance and doesn't involve a chemical reaction to take place between the water and the oil. No new materials or substances are formed.

because each of the objects displaced the water by 1 mL, their mass over that mL is their density.

Density is the amount of matter per unit of measurement (Merriam-Webster. Merriam-Webster, n.d. Web. 26 Aug. 2016.). If water has a density of 1.0 g/mL and you place a substance with a density of 1.8 g/mL the substance will sink because it is denser than water. Density is often measured in g/cm^3 or g/mL because the formula for density is D=m/v.

Density was an important part of this lab. Density can be defined as the ratio of the mass of an object to the volume. To find the density of an object, simply divide mass and volume. The equation looks like this: D=M/V. Density is an intensive property that depends only on the composition of a substance, not the size of the sample.

This hypothesis is based off of the idea of water density and how it changes when a substance is added or removed. A material's density is defined as its mass per unit volume. It is, essentially, a measurement of how tightly matter is crammed together (Jones, 2015). Every matter in the world has its own specific density. Density can be calculated by multiplying the mass times the volume. Water's density can change when a substance is added or when the temperature is increased or decreased with the normal density of water is just under 1 gram per

If I fill up two different containers with different amounts of water, then I will be able to understand the density of the two different mass/volumes of two different containers.

In the Chemistry of Natural Waters Lab we were to collect a sample of water, ranging from a fountain, stream, bottle, or tap water. After we collected the samples we all did many tests to see what the hardness was for each one. Water hardness is determined by the amount of Calcium and Magnesium in the water.(2) Water that has more Calcium or Magnesium is considered to be harder than water with less of those two elements. When you use soap and detergent, this is where you see water hardness coming into play in everyday life when you are washing things.

2. In order to calculate the density of a solid or liquid sample, what measurements are needed?

(Lab: A Penny For Your Thoughts). The density of a matter is equal to the mass divided into the volume. The mass of a matter or object can be found by using a scale. Furthermore, the volume can be found using the method of water displacement. The purpose of finding

In Measuring and Understanding Density, several experiments were performed to find density of regularly shaped objects, irregularly shaped objects, liquids and gasses. An additional experiment was done to find the specific gravity of a sampling of liquids. The purpose of the experiment was to provide a better understanding of density and to be able to extrapolate unknowns based upon these calculations. The experiments yielded data in keeping with Kinetic-molecular theory in regards to the density of water versus its temperature. Key measurements and formulae were also used to determine densities of metal and plastic objects as well as irregularly shaped rocks. It is possible to find the density of an object (be it liquid, gas or

The goal of this experiment was to determine the empirical formula for a hydrate of magnesium sulfate and water. The technique that was used was measure the mass of the hydrate and then apply heat to evaporate the water. Then determine the mass of water that was in the hydrate and the mass of the remaining magnesium sulfate. The equation for the hydrate is determined by calculating the mole to mole ratio of the water and the anhydrous. The resulting formula will be formated as: MgSO4*_H2O

In this lab, the calculations were based upon mass, volume and their relationship to density. However, a couple of errors made our results have variations. First of all, the graduated cyinder in which the table salt plus water was added was a little wet. So the extra drops of water contributed to the whole mass of the table making out results a little different from the known results. Also, in the “Measuring the density of bearing balls” lab, the diameter of the balls was difficult to measure because of the shape. The balls were spheres and

Density is an important property of matter because every object has a unique number of density associated within it. It is how we find out out if an item will float or not and the compactness of an object.

Density is the mass compared to the ratio of volume. Different substances and different temperatures can cause different things to react differently, causing the density of an object to be higher or lower. A lot has to do with the material as well. Regardless of the temperature metal will usually be denser than a light object such as a Styrofoam

Discussion: The aim of the experiment was to be using filtration techniques to help craft a makeshift water filter. The hypothesis for the experiment was that the dirty water containing dirt, rocks, trash and chemicals would all be separated by three fine screens, activated charcoal, sand, and tissue. This would keep out the unwanted materials and eventually filter into purified water.
