Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

Imagine that unknown gas in the storage tank is analyzed. A 14.74-g sample of the gas contains 9.97 g N2, 1.39 g CH4 , and 2.65 g CO2. Calculate the partial pressures of each gas (in bar) in the storage tank if the total pressure in the tank is 3.15 bar.

Is there evidence that the amount of product formed is related to the amount of reactants used? Is there evidence that some of the baking soda has not completely reacted in one or more of the bags? Open each bag and add 15mL of vinegar to each. Is there evidence that a shortage of vinegar was limiting the production of carbon dioxide gas in some bags? Add 15mL of baking soda to each bag. Is there evidence that a lack of baking soda was limiting the production of carbon dioxide in some bags?
To determine the molecular weight of an unknown chlorate. a sample of the chlorate was decomposed by heating and the oxygen gas produced was collected over water.563mL of oxygen were collected. The gas collected and the water were both at a temperature of 24°C. The total pressure of the room was 0.996 atm.

A sample of O2 gas is observed to effuse through a porous barrier in 7.64 minutes. Under the same conditions, the same number of moles of an unknown gas requires 12.7 minutes to effuse through the same barrier. The molar mass of the unknown gas is g/mol.

A sample of SO2 gas is observed to effuse through a porous barrier in 5.45 minutes. Under the same conditions, the same number of moles of an unknown gas requires 4.27 minutes to effuse through the same barrier. The molar mass of the unknown gas is g/mol.

Match the characteristic of gases described below to the postulates of the kinetic molecular theory that best explain that characteristic. (Note: You may need to list more than one postulate.) The pressure of a gas in a fixed volume increases when its temperature increases. Select one or more: The average kinetic energies of gas particles increase with an increase in temperature. Gas particles are widely spaced. A gas consists of many small particles in rapid, random motion. The total volume of the molecules themselves is very small compared to the volume of the container. There are virtually no attractive forces between gas particles.
A student obtained a mass of 0.266 g CO2 during his experiment. The atmospheric pressure was 751.6 mmHg and the laboratory temperature was 24.1 °C. The flask used in the experiment had a volume of 146.5 mL. Calculate the molar mass of CO2 from the data. Hint: You cannot use the molar mass of CO2 in your calculation since this is what you are looking for... You need to used the ideal gas law to determine the number of moles of CO2, then do the ratio of grams of CO2 over moles of CO2 to determine the experimental molar mass of CO2.
A gas of unknown molecular mass was allowed to effusethrough a small opening under constant-pressure conditions.It required 105 s for 1.0 L of the gas to effuse. Underidentical experimental conditions it required 31 s for 1.0 Lof O2 gas to effuse. Calculate the molar mass of theunknown gas. (Remember that the faster the rate of effusion,the shorter the time required for effusion of 1.0 L; inother words, rate is the amount that diffuses over the timeit takes to diffuse.)
A cylinder is filled with 10.0L of gas and a piston is put into it. The initial pressure of the gas is measured to be 281.kPa . The piston is now pushed down, compressing the gas, until the gas has a final volume of 1.90L . Calculate the final pressure of the gas. Be sure your answer has the correct number of significant digits.
