Volume ratio

mass and volume from the small pieces of clay from all three trials and I find the average which is 14.7g (mass) and 8.7cm3 (volume). Then I divide using thee formula d=m/v and for density I got 1.7g/cm3, rounded to the nearest tenth. Next I did the same for medium of all three trials in which I got 22.5g for the average of the mass and 13.3cm3 for the volume. I divide using the same formula and also got 1.7g/cm3, rounded to the nearest tenth. Lastly I find the average of mass and volume for large

GS104 Lab Report Experiment # 1 Measurement, Length, Mass, Volume, Density & Time David Case: January 17, 2015 Experiment #1 Measurement, Length, Mass, Volume, Density, & Time Objectives: To make basic distance, mass, density, and time measurements. To make calculations of volume and density, using proper units, and to practice using graphing software while graphing the relationship between the circumference of a circle and its diameter. Materials:

Hypothesis The objective of the density determination lab is to determine/compare the average density of pre-1982 and post-1982 pennies. This can be achieved by finding the mass to volume ratio then averaging the results. The purpose of this lab is to find out if the difference in composition of the pre and post pennies will affect their densities. Pennies made before 1982 where majority copper but pennies minted after 1982 are made with mostly zinc. With this background knowledge, we expect the

more accurate and hence better to use in such a case. The two methods used in this experiment are finding the dimensions of the object and water displacement. These are two ways of finding the volume of an object, and they were chosen since the density of an object may be found using its mass and its volume. The experiment yielded two different density values, however when error analysis was conducted, the water displacement method was proven to be more accurate. INTRODUCTION

It used mass, temperature, length, volume, density, and making a dilute solution. I learned the importance as well as the difficulty of making proper measurements in a lab setting. If one measurement is off, it will throw the entire equation off. This will give either incorrect or inaccurate

ultimately find the volume of the warehouse at that given height of the model. The derivative function of the semicircle for any height (greater than or equal to 36, less than or equal to 54) is shown below: We used this equation to generate different heights that would maximize the area of the cuboid. We were able to isolate just the area of the cuboid because that one face is simply projected backwards 150m, so we mathematically we were able to ignore that constant in the volume equation shown above

The objective of this experiment is to determine the correlation between a solution’s salt concentration and its density. Also, it was to determine what equipment would be best to use to measure volume precisely and accurately. Densities of a series of known salt solutions were trialed three times and then averaged. By following the procedures, the unknown salt solution was determined and graphed to calculate the percent salt to the sample. Introduction In chemistry there are often times an unknown

“paths” from the sides of the body that are capable of releasing this heat particles, and reaching thermal equilibrium faster. This is what happens when a hotter body is subjected to a colder one. Research Question: How does the surface area to volume ratio affect

calculate the density of a solid or liquid sample, what measurements are needed? Mass and volume 3. The volume of a fixed mass of a liquid sample increases as the temperature rises from 20 to 408C. Does the density increase, decrease, or stay the same? Explain your answer. The density decreases. Density of the liquid sample is the mass divide by the volume. If the mass stays constant and the volume increases then the density of the liquid sample will decrease. 4. A solid block of exactly
