In summary, the Victor Meyer method uses an equation that includes the standard and experimental volumes, room temperature, barometric pressure, water meniscus height, and vapor pressure of water. The ratio of the triple point of water to the room temperature is taken to convert the temperature to an absolute scale. The correction for barometric pressure is given by the third multiplier, which is h/13.6, where 13.6 is the specific gravity of mercury.

1. Homework Statement
I have this equation used for our experiment, which was Weiser's modification of the Victor Meyer method. Can someone help me understand this equation?



2. Homework Equations
http://postimage.org/image/mzmj5ammj/f7e660f1/


Vs = standard volume
V= experimental volume
t = room temp
P= barometric pressure
h=height of water meniscus
w=vapor pressure of water at the specified room temp




3. The Attempt at a Solution
1) why take the ratio of the triple point of water (or melting point?) to the room temperature?

2) i understand that the correction for barometric pressure is given by the third multiplier. why h/13.6, what is this quantity?? 13.6 is the specific gravity of mercury, btw

Hard to say anything seeing just a tiny fraction of the formula.

Temperature ratio is there to convert t to kind of an absolute scale.
 

FAQ: Question regarding victor meyer method

What is the Victor Meyer method?

The Victor Meyer method is a technique used in chemistry to determine the vapor pressure and molecular weight of a substance. It involves heating a known volume of the substance in a closed vessel and measuring the volume of gas produced at a known temperature and pressure.

How is the Victor Meyer method performed?

The Victor Meyer method involves a three-step process. First, a known volume of the substance is placed in a flask with a small amount of a liquid that will react with the substance. The flask is then sealed and heated, causing the substance to vaporize and react with the liquid. The volume of gas produced is measured and used to calculate the vapor pressure and molecular weight of the substance.

What are the advantages of using the Victor Meyer method?

One advantage of the Victor Meyer method is that it can be used to determine the vapor pressure and molecular weight of substances that are difficult to measure using other techniques. It also requires relatively simple equipment and can be performed quickly.

What are the limitations of the Victor Meyer method?

The Victor Meyer method can only be used for substances that are volatile enough to be vaporized at the temperature and pressure used in the experiment. It also assumes ideal gas behavior, which may not be accurate for all substances.

How accurate is the Victor Meyer method?

The accuracy of the Victor Meyer method depends on several factors, including the precision of the equipment used and the skill of the experimenter. With proper technique and equipment, the method can provide results with an accuracy of within 1-2%. However, it may be less accurate for substances with high molecular weights or low vapor pressures.
