Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

Produce Water mass “X” is known to be a mixture of water masses “1”, “2”, and “3”. Using the data plotted below, calculate the composition of “X” (i.e. determine the fraction from each of the 3 water masses that makes up water mass X). Watermass#1– SF6 =25 S=33.5 Watermass#2– SF6 =75 S=32 Watermass#3– SF6 =50 S=36.5 Water mass X – SF6 =60 S= 34
A core sample is saturated with an oil (?o = 35oAPI), gas and water. The initial weight of the sample is 224.14 g. After the gas is displaced by water (?w = 1 g/cm3 ), the weight is increased to 225.90 g. The sample is the placed in a Soxhlet distillation apparatus, and 4.4 cm3 water is extracted. After drying the core sample, the weight is now 209.75 g. The sample bulk volume, 95 cm3 is measured in a mercury pycnometer. Find the porosity, water saturation, oil saturation, gas saturation and lithology of the core sample.

a Table: (This is an example of what your data table should look like.) Pressure (kPa) Temperature (°C) Temperature (K) Constant, k(P / T or P•T) Ice water bath 91.58 2.4 275.55 Room temperature 96.54 21.1 294.25 Warm water 104.11 44.5 317.65 Boiling water 113.75 77.5 350.5 Calculations: One way to determine if a relationship is inverse or direct is to find a proportionality constant, k, from the data. If this relationship is direct, k = P/T. If it is inverse, k = P•T. Choose one of these formulas and calculate k for the pairs in your data table (divide or multiply the P and T values). Record the answers in the fourth column of the Data table. How constant were the values for k you obtained in Question 4? Good data may show some minor variation, but the values for k should be relatively constant. Comment on your calculated k values. Analysis Questions: What does temperature measure?

The volume of the mixture prepared by taking 1.158 mol and 0.842 mol of water and ethanol, respectively, was measured as 68.16 cm3 at 25 ° C.Since the partial molar volume of water in the mixture is 16.98 cm3 / mol, find the partial molar volume of ethanol.Since the densities at 25ᴼC for pure water and ethanol are given as 0,9970 g / cm3 and 0,7852 g / cm3, respectively, find the volume change during the preparation of the mixture and interpret the result. (MSu: 18 g / mol; Methanol = 46 g / mol)
