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".

The total cation content of natural water is often determined by exchanging the cations for hydrogen ions on a strong acid ion-exchange resin. A 25.00 mL sample of a natural water was diluted to 100.00 ML with distilled water, and 2.06 g of a cation - exchange resin was added. After stirring, the mixture was filtered and the solid remaining on the filter paper was washed with three 15.00 mL portions of water. The filtrate and washings required 16.30 mL of 0.0282 M NaOH to give a bromocresol green end point. a) Calculate the number of millimoles of cation present in exactly 1.00 L of sample. b ) Report the results in terms of milligrams of CaCO3 per liter. Only typed solution.
A 4.36-g sample of an unknown alkali metal hydroxide is dissolvedin 100.0 mL of water. An acid–base indicator is added,and the resulting solution is titrated with 2.50 M HCl(aq)solution. The indicator changes color, signaling that theequivalence point has been reached, after 17.0 mL of the hydrochloricacid solution has been added. (a) What is the molarmass of the metal hydroxide?

For an experiment you are measuring the decomposition rate of organic matter, You have a large amount of CH402 in a container filled with 3.024 Lof water. You Created a saline environment by adding 2.4 g of sodium chloride, 3.6 g of calcium chloride, and 2.8 g of magnesium chloride before diluting. iron (1) oxide is available for the microbes to oxidize the matter into carbon dioxide by forming iron (II) aqueous ions. At the beginning of the experiment, you measure the pH using a probe to be 7.13. After 73 hours you measure the pH again and obtain 7.54. Assuming that the pH change is solely due to the oxidation of organic matter, what is the rate of organic matter decomposition in nanograms per hour?

One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate, Suppose an EPA chemist tests a 200 mL sample of groundwater known to be contaminated with iron(III) chloride, which would react with silver nitrate solution like this: FeCl,(aq) + 3 AgNO,(aq) 3 AgCl(s) + Fe(NO₂),(ag) The chemist adds 21.0 mM silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the precipitate. He finds he has collected 3.3 mg of silver chloride.

Suppose a group of volunteers is planning to build a park near a local lake. The lake is known to contain low levels of arsenic (As). Therefore, prior to starting construction, the group decides to measure the current level of arsenic in the lake. If a 11.7 cm³ sample of lake water is found to have 172.3 ng As, what is the concentration of arsenic in the sample in parts per billion (ppb), assuming that the density of the lake water is 1.00 g/cm³? concentration: ppb One of the volunteers suggests hiring an on-site water treatment company to remove the arsenic from the lake. The company claims their process takes 2.98 days to remove 31.30 kg of arsenic from a water source. Calculate the total mass, in kilograms, of arsenic in the lake that the company will have to remove if the total volume of water in the lake is 0.950 km³. total mass: kg
