## Lab: Molar Mass of Butane

Until then, keep all the digits and decimals as is practical. The concepts of mass density, standard error, average, one-dimensional statisticsâ€¦ 1676 Words 7 Pages The Ka and Molar Mass of a Monoprotic Weak Acid Chemistry Lab 152 Professor: James Giles November 7, 2012 Abstract: The purpose of this experiment was to determine the pKa, Ka, and molar mass of an unknown acid 14. Determine the empirical formula of butane based on your data. It focuses on the difference between their spectrums. This would make the moles larger.

## Determining the Molar Mass of Butane

Hypothesis My hypothesis is that as we complete the experiment, we will be able to correctly use the air and water temperatures, volume of gas, and barometric pressure to correctly calculate the molar mass of butane Procedure At first, gathered all of the materials. Walter Snellings in Pittsburg and he gas is used for cigarette lighters, heaters, stove fuels, and other heating appliances. At the very least review , , and. This is what limits your end result to three. When calculating the moles, if the pressure of water vapor is not corrected, when using the ideal gas law, the product of the pressure and volume would be significantly larger. The molar mass of carbon is approximately 12. After mixing these chemicals together, we boiled the flask until all the liquid in the solution was gone.

While having the cylinder held slightly at an angle the lighter was placed underwater and under the cylinder, and the butane gas was released into the graduated cylinder. One potential area of confusion with regard to butane mass: Even though your measured masses have 6 sig figs, the mass of butane you get from subtraction only has three because in addition and subtraction, you only keep as many decimal places as you had in your raw data. However, along the way, you want to disregard sig figs and hold onto enough digits and decimal places so that you do not develop a significant error due to rounding, especially in long calculations. After further calculations, the molarity of the butane gas was calculated to be 56. So, if you have 4.

The results of this lab were the mass of the lighter, as 100 mL of water was displaced, was 0. The graduated cylinder was then filled completely. That being said I really want to do well on this lab, and I'm a bit frustrated considering that it seems quite simple. You also know that the pressure inside the cylinder has contributions from both the water vapor pressure and the butane. Butane was discovered by Dr.

Some of the light sources included are sunlight and a candle. The measurements in the lab are reliable taking into consideration the equipment windows of error and there are few to no flaws and weaknesses in the procedure itself. The gas collect ion tub e was fill ed with w ater and t urned u psid e down , after cov ering the cylinder with a stopper a hand. Students should not be allowed to play with the lighters. Also, the butane used in the experiment could have been certified as pure butane, rather than butane from a common lighter. You ultimately want to use the ideal gas law to determine the moles of butane inside the cylinder so that you can calculate molar mass of butane.

Position the lip 1-2 cm below the water surface. This temperature was used to a pproximate the temperature of the gas. Try to think of others. P represented the pressure which can be found in step 6. Please flair yourself and read over the rules below before posting.

The more trials completed, the closer the average molar mass of butane is to the accepted value of the molar mass of butane. . An Alkane is when the compound is formed by single bonds connecting the carbons and hydrogens. Background: The Molar Heat of Combustion of a substance is the heat liberated when 1 mole of the substance undergoes complete combustion with oxygen at standard atmospheric pressure, with the final products being carbon dioxide gas and liquid water. A decibel is a unit used to measure the intensity of a sound.

The pressure of the gas would be higher. Ok with that out of the way. The way we had done this experiment is by setting 10 meters of tape, each person stands on a meter with their cellphone. Walter Snellings in Pittsburg and he gas is used for cigarette lighters, heaters, stove fuels, and other heating appliances. I am trying to go Pre-Vet so I know I have plenty of chemistry ahead of me, and I am trying to master good lab habits now while it is early in the game. It is basically to see the spectrum of different light sources.
