chemistry. In this lab‚ the ideal gas law helps determine and evaluate the molar mass of gases and volatile liquids. The ideal gas law compares four properties of a gas which include pressure‚ volume‚ moles‚ and temperature. During this experiment‚ the moles would be unknown‚ in effect the student must use a substance mass divided by its molar mass. With this‚ the ideal gas law can be arranged in an equation fit for helping the student determine the molar mass of a gas. Purpose: The purpose of the lab

fracturing. Physical and Chemical Properties At normal pressure‚ liquid nitrogen boils at 77 K (−195.8°C or −320.4°F).The liquid to gas expansion ratio of nitrogen is 1:694‚ which means liquid nitrogen boils to fill a volume with nitrogen gas very quickly.Nitrogen is non-toxic‚ odorless‚ and colorless. It is relatively inert. It is not flammable.Nitrogen gas is slightly lighter than air once it reaches room temperature. It is slightly soluble in water. Storage liquid nitrogen is usually

cooling system(VCCS) is to give accurate cooling at aircraft cabin and also to rremove heat from electrical and electronic equipment. Its work on principle of cooling based on ability of refrigent to absorb heat when changing from liquid to gas. Once it turns to gas all the latent heat of vaporization it is compressed and condensed back into its liquid state. In other way vapour cycle system his also help to reduced the humidity of the air entering the cabin while aircraft on the ground and as the temperature

distillation method was used to divide hexane and toluene from a mixture (50:50) of hexane and toluene. Hexane was separated from toluene and was observed from the gas chromatography‚ it showed that hexane increased from 0.0.873 to 0.886 moles. Once the mixture of toluene and hexane hit 70 degrees in the experiment‚ the distillate was used for the gas chromatography. Hexane was higher in the distillate stage. The first drop of condensation appeared at 79°C. The volume of the distillate was 0.88ml and 0.98ml

Exercise 1. What safety equipment is available to you while you do your experiments? How far are they from you while you are conducting your experiments? This includes fire extinguishers‚ phones‚ showers‚ etc. The safety equipment that I have access to while performing my experiments are as follows; shower‚ fire alarms and a telephone. They are all within ten feet from where the experiment will take place. 2. What is an MSDS? MSDS is a document that is required by Osha’s “Hazard

is to acquire the use of common and simple laboratory equipment. Brief Procedure: A Bunsen Burner: Examine burner‚ locate gas and air flow‚ determine the operation of each valve. Connect the Bunsen burner to a gas tap using a piece of rubber tubing.Close the needle valve and the air vent. Open the gas valve. Open the needle valve 1-2 full turns‚ listening for the sound of gas. Using the striker‚ light the burner. The flame of the Bunsen burner should be yellow and irregular in shape. Open the air-hole

ways to find the molar mass of a substance. One way‚ if the substance is a gas‚ is to use the Ideal Gas Equation to find molar mass. The standard equation reads PV=nRT where “n” is the number of moles present‚ “P” is the pressure (which is obtained by reading the barometric pressure of the room with the class barometer)‚ “V” is the volume of the gas‚ “R” is the universal constant‚ and “T” is the temperature of the gas. The experiment’s objective is to calculate the experimental value of molar mass
