Molecular weight of a condesable vapor

Write the ideal gas equation; define and specify the unit for each variable. The variable n can be written as Substitute this quotient for n in the ideal gas equation and solve for the molar mass. Describe the experimental data which would be needed to determine the molar mass of an unknown gas.

Molecular weight of a condesable vapor

How to Write a Summary of an Article? The purpose and objective of this lab was to find the molecular weight of a condensed vapor. The square of aluminum was fashioned over the flask by laying the foil over the mouth and folding the sides down. A pin was then obtained and was used to poke a tiny hole in the center of the aluminum cap.

Next, the mass was determined of the clean, dry flask with the cap to 0. Afterwards the flask cap was replaced securely.

Then, a mL beaker was then filled nearly full of water. The beaker was then heated to a boil over the Bunsen burner setup. Once the water reached a boil, the temperature was then recorded and the barometric pressure. Then the flask was clamped at the very top and was suspended to the beaker.

The flask from the beaker was not removed and the flask was examined for excess vapor coming out through the pin hole to see a refraction effect. When all of the liquid evaporated, the flask was removed by holding the clamp and set aside to cool.

Next, the flask was wiped down until it was completely dry. Then, the mass of flask, cap, and unknown condensed liquid was found. The flask was filled completely full with water. The flask was then poured into a graduated cylinder and measured the volume.

Next, all the materials and chemicals were cleaned up. Once the area was clean, the calculations could be completed. The flask inside the beaker full of water was being examined. As the water surrounding the flask began to boil, droplets started to form on the inside of the flask.

After a while, nothing could be seen forming in the flask. When this happened, the droplets evaporated and inside the flask was the condensed vapor. What does the flask contain? The flask contains air before adding the volatile liquid. The flask contains all vapor at the point when the volatile liquid has completely vaporized.

The flask contains condensed vapor and air at the end of the experiment and at the final weighing. Why is the temperature of boiling water used for measuring the volume of the vapor instead of the temperature of the liquid after it has cooled to room temperature?Molecular Weight of a Condesable Vapor.

Background: ideal gas law

Topics: Water, Molecular Vapor Deposition (MVD) is a unique nanotechnology technique that allows for room temperature vapor deposition of organic and organometallic molecules. MVD technology enables the growth of ultra-thin films with a wide range of functionality on a broad spectrum of substrates.

Set. The term vapor is often used to describe the gaseous form of a substance which exists as a liquid or a solid under ordinary circumstances. Standard temperature is defined as K; standard pressure is defined as 1 atmosphere, or torr. Vapor Pressure and Heat of Vaporization Introduction:?Evaporation is the process of a liquid becoming vaporized.

When a liquid is placed into a confined space some of the liquids will evaporate. Evaporation of the liquid depends on the strength of the intermolecular forces that are between liquid molecules.
