Bone density

ratio of M-S-H binder In development of M-S-H binder with magnesium oxide and silica fume, it is noted that silica fume has rather low specific gravity (S.G) and bulk density compared to Portland cement (PC). Thus, use of high silica fume content in the binder consequently results in a binder system of low specific gravity and bulk density, compared to PC. The light weight binder leads to a difference in water to binder ratio (by mass), compared to PC. To compare water content by mass of M-S-H…

When the egg was placed into syrup, a hypertonic solution, it shrunk in size. This result supports my hypothesis. The mass of the egg before it was placed in syrup and after it was placed in syrup changed drastically. There was a 16 g decrease in mass that happened to the egg during its time in the syrup. Both the long and short circumference of the egg decreased. The long circumference before the egg was placed in syrup was 18.75 cm and after it was taken out of the syrup the long circumference…

of the eggs is greater than the density of water. Then salt water 1-2 a spoon and stir in the eggs slowly, still also sank because of the eggs is still greater than the density of water. Drift An object that is dipped into the liquid will float if heavy objects are similar in style to the top or the object in equilibrium By the time the water was given a 2 ½ spoon of salt and stir gradually then egg will be on a State of drift. This happens because the density of water is equal to the mass…

Lab 4 in Chem 115 has three parts all calculating density. In part one, a 100 mL beaker, a volumetric pipet, and an analytical scale were obtained. To begin, the mass of the beaker was taken using an analytical scale. Then, 10.0 mL of an unknown liquid was transfered to the beaker using the volumetric pipet. Next, the mass of the beaker and liqiud was recorded along with the letter identifying the unknown liquid. By subtracting the mass of the 100 mL beaker from the mass of the beaker and liquid…

In this experiment the students were required to provide urine samples three times in 60 minutes. This experiment was done to test urine volume, flow rate, total dissolved solids, and pH at each interval and record the differences in these variables depending on what each participant was asked to eat or drink. I hypothesized that the subjects asked to eat pretzels and drink soda would see an increase in total dissolved solids in their urine. In this experiment the 20 test subjects had to provide…

Data Calculated from Experiment Solid-Liquid Weight (g) Solid-Liquid % Recovery Liquid-Liquid Weight (g) Liquid-Liquid % Recovery Acid 0.01 20 % 0.028 56 % Phenol 0.011 22 % 0.001 2 % Amine 0.013 26 % 0.005 10 % Neutral 0.03 60 % 0.026 52 % Table 1 shows the data obtained from this experiment of both the solid-liquid extraction (on the left side of the table) and the liquid-liquid extraction method (on the right side of the table). It shows that in the solid-liquid extraction, most of the…

AIM OF THE PRACTICAL The aim of this practical was to investigate the reality or the accuracy of the formula for the resultant force on and the position of the centre of pressure on a vertical rectangular surface. SKETCH OF APPARATUS Counterbalance weight Balance pan(with 20g mass piece) Flat/curved surface(as shown below) Water Beaker Mass pieces(20g each) SUMMARY OF THEORY Hydrostatic force is the force exerted by the…

to push it up causing it to float; the less density of the boat the nearer to the surface the vessel floats. The boat…

three questions in regards to density. The first question inquired which method of density calculation would be the most accurate. The second question asked if the sugar in the soda had an effect on its density. The third question stated what affect the varying size and shape of the copper pieces had on their density. These questions were explored in the experiment and some interesting conclusions were made at the end. In the first half of the experiment, the density of copper is calculated…

Objective- Our goal for this lab was to calculate the Density of a substance. We needed to make sure we had the materials to find mass and volume and then use a formula to calculate density. Introduction- The main principle of this experiment was to figure out the Density of certain objectives given to us in the lab. We had to know the the formula D-M/V in order to find the density of that object.We also needed to know the density of water(1.0 g/l) in order to predict if something would float…
