Population density

water into the beaker, and then reweighing the beaker. Next, the weight of water was calculated by subtracting the weight of the empty beaker from the weight of the beaker containing water. These values were then converted to water volume using the density of water at a temperature of 19.5 °C; 0.998 g/ml. The weight of water measurements, 9.82 g, 9.90 g, and 9.94 g, were converted to water volume by dividing by 0.998 g/ml as shown below. Volume = (9.82 g) / (0.998 g/mL) = 9.84 mL Volume =…

Introduction A vessel floating in water reacts to its environment with motion. It has six degrees of freedom, three translational and three rotational. When the floating vessel is attached to appendages, which in this case is mooring lines and risers, these attached slender structures also have effect on how the vessel reacts to the environmental loads. This study is to understand how these effects are analysed. In this chapter, the solution of the uncoupled and coupled analysis is going to be…

Injection Machine 4.6.1 Calculation of the Injection Volume Figure 4-8 shows the volume of plastic parts by Solidworks modeling. Figure 4-8 Volume of the Stress Cone Plastic parts volume: Vplastic = 4.198 × 10-5 m3 = 41.98 cm3 Plastic parts density: ρ = 1.2 g/cm3 Plastic parts quality: mplastic = ρVplastic = 1.2 × 41.98 = 50.376 g 4.6.2 Preliminary Estimation of the Gating System Although the gating system of condensate cannot determine the exact value prior to design, it can be…

Our experiment was centered on taking four testing groups and setting a baseline level of dehydration across all four groups. From there each group would be assigned water, coke, Gatorade or remain dehydrated. The test subjects would then consume their assigned drinks based on their body weight. Urine would then be collected at thirty-minute time intervals to measure urine changes. The goal of our experiment was to determine the influence of fluids being introduced into the body of various…

Aim The aim of this practical is to measure the effect of volume, density and temperature. It is also help to be familiar with variety of common laboratory technique. Materials Weighting scale Container with lids 20 and 10 ml Volumetric pipette Beaker Thermometer Test Tubes Volumetric flask Natural Rubber Pipette Filler Micropipette tips Tips boxes Method There are two pipette, choose one which you using in whole practical. Label and weight accurately, to 4 decimal places. Collect…

By examining Figure 4, we can see the relationship between density and molar mass to be a proportional relationship. The positive slope of the scatter plot confirms this relationship. This means that as molar mass of is greater, the density of the gas will also be greater, and if the molar mass of a gas is smaller, the density of the gas will be smaller. For example, hydrogen gas will have a lower density than nitrogen gas because hydrogen has a smaller molar mass than nitrogen.…

The Relationship between Mineral Type and Density (g/ml) Purpose/Introduction: The purpose of this lab was to understand the relationship between minerals and density, the ratio of mass to volume, particularly, how density can be used to identify mineral type. In the lab, two samples of the mineral, feldspar, were measured for mass and volume in order to calculate their density. Many of the mineral tests yielded qualitative data, such as color, streak, luster, and crystal shape, which can be…

Experiment 2: Aim: In this experiment you will determine the mass of a single drop of water by a graphical method. You will evaluate its uncertainty. Data: Table 1: Number of Drops: Mass of Beaker + drops/g (0.01g) 1 2.36 g 2 2.38 g 3 2.40 g 4 2.44 g 5 2.46 g 6 2.48 g 7 2.50 g Chart 1: Analysis: The mass of 1 drop of water is 0.4g. By taking the total mass and dividing it by the number of drops we can figure out the average mass of a drop of water. However the number of drops should…

An introduction to the Balance and the Determination of Density Purpose: To make measurements and collect data to determine the physical properties of matter; density, volume, and mass. Materials: Graduated Cylinder Balance Water Unknown Liquid Paper Towels Weighing Paper Weighed Solid (Rubber stopper) Procedure: Part A Obtain a 10 ml graduated cylinder and measure its mass on the balance. Record. Pour water inside the graduated cylinder. In other to get the correct measurement of volume, read…

the volume lab, we found that the large graduated cylinder was the most accurate because it had less percent error when measuring the density of water over all of the other measuring tools.In this lab, we measured water from pipettes including volumetric and graduated pipettes, graduated cylinders, erlenmeyer flasks, and beakers to figure out the mass and density. These measurements were then used to calculate the percent error. We completed these measurements by measuring the volume of the…
