Introduction Molar volume is the name given to the volume that one mole of any gas occupies at standard temperature and pressure. In chemistry‚ many of the materials worked with are gases. It is often easier to measure the volume of a sample of gas‚ rather than determine its mass. The main purpose of this lab is to determine the molar volume of hydrogen gas experimentally in order to compare it to the theoretical molar volume of ideal gases. In this experiment‚ a known mass of magnesium is reacted

study of thermodynamics. Substances such as gases and vapors are often referred as P-V-T substances. Theory: An ideal gas obeys the equation of state that the pressure‚ specific volume or density‚ and absolute temperature with mass of molecule and the gas constant‚ R. PV = mRTM Where‚ P = Absolute pressure V = Volume n = Amount of substance (moles) R = Ideal gas constant T = Absolute temperature (K) However‚ real gas does not absolutely obey the equation of state.

Physical Chemistry CHM2330 Experiment F- Raoult ’s Law Experiment By: Sanah Assaad Student Number: 5267864 Partner: Jihad Arafa T.A: Didier University of Ottawa March 25‚ 2010 Objective: The purpose of this experiment is to study the total vapour pressure of ideal or non-ideal mixtures of two volatile liquids as a function of chemical composition. Introduction: For ideal mixtures of volatile liquids the vapour pressure of any given mixture may be obtained by applying Raoult

Method 1) Take a "volume" measuring device‚ and fill it with the total amount of water‚ the bottle can hold. We then put the same‚ empty bottle into the container‚ in a way‚ that it sinks to the bottom of the akwarium. We can then measure the new height and multiply it by the volume of the liquid. This will clearly give us the volume of a bottle. Method 2) We could pour water into a 0‚5 litre coke bottle‚ and weigh how much it would weigh. We could do the same thing with an empty bottle. The

Adsorption Experiment This paper will be discussion the adsorption experiment conducted in Dr.O lab class. This paper will cover what Chitin/Chitson are but before explaining what these are it is best to get an understanding of what adsorption‚ absorption and sorption are. Adsorption is the accumulation of gases‚ liquids‚ or solutes on the surface of a solid or liquid. This binding is very weak. Almost anything such as fluids that dissolves can break the binding of the molecules. In addition adsorption

a tremendous variety of oxidation states that appear in its compounds. The oxidation numbers range from Mn (III) in compounds like Mn(NO)3CO to Mn (VII) in KMnO4. Compounds of manganese range in oxidation number between theses two extremes. This experiment involves the preparation of a Mn (III) complex of actylacetone (also named 2‚4-pentanedione) which is a useful starting material for the preparation of other Mn (III) compounds. Manganese (III) complexes are relatively stable and can be prepared
