Using elemental analysis to determine the percent mass composition of each element in a compound is the first step in creating an empirical formula. There are many different types of elemental analysis, but in this experiment gravitational analysis and Beer’s Law are used. Elemental analysis is first used to find the moles of each element, then converted to mass, and then the percent mass of the element in the product is found (2).

Purpose: To find the relationship between the mass and the volume of the four samples.

An unknown sample is identified using the relationship between the mass of the product and mass of the reactant in a balanced chemical equation using the involved species molar mass.

If we measured in meters then a=4.9.) t is the time in seconds, v0 is the initial velocity of 30 feet per second, and s0 is the initial height or 4 feet. Thus we have:

Task M2.1 – Relationship between landing gear weight switches and the nature of the landing gear indications and warnings.

The purpose of this assignment is to work out a parachute design and investigate parachute’s drop time. Parachutes are designed to fall slowly so that the person can land safely to the ground, as shown in figure 1. Parachutes are big, but not heavy and have a larger surface area for air resistance like traps the air from escaping out of it. This is because the air pushes the parachute back up, but the force of gravity pulls the parachute to the earth.

3. we used percent change because it shows the direct relationship between the final mass and initial mass clearly.

Write down three sources of experimental error and explain how each one might have affected your final calculated molar mass.

Any deviation identified during the evaluation is analyzed and classified into one of the three buckets:

After that, it is crucial to convert the mass to volume. The water density at a temperature will aid this process. The compliance of the Volume Occupied by 1.000g of Water Weigh in Air table is deemed necessary throughout the comparison.

The purpose of this lab was to test the law of conservation of mass by comparing the total mass of the reactants in a chemical reaction with the total mass of the product.

Conclusion: The result supports the hypothesis, that as the mass increases so will the force as there is a general trend that shows when mass is increased so is the force.

5. When both the design and the measurement specifics have been determined, a test is needed to assure that they are feasible for the purposes intended. Almost certainly deficiencies requiring revisions and additional testing will be found at this stage.

Case II: The beam was turned around in such way that the shortest side of the cross section is on the support. The steps described in Case I was repeated and data was recorded.
