What is the volume (in liters) of this air sample if the pressure is changed to 0.960 atm at a constant temperature? Do not includethe unit of meașure in your answer. Breathing is an application of Boyle's law (Figure 10.8). As the diaphragm muscle beneath our lungscontracts, the pressure inside our lungs decreases, causing air to rush into our mouth and nasalpassages to fill the lungs. When the diaphragm muscle relaxes, it increases the air pressure, causing air tobe expelled from the lungs. A typical lung volume is 3.50 liters (L). Air pressure inside the lungs changesby approximately 0.040 atm. A sample of air has a volume of 3.50 L at 1.00 atm. But how do wedetermine the volume of this air sample if the pressure is changed to 0.960 atm at constant temperature?

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

Question

What is the volume (in liters) of this air sample if the pressure is changed to 0.960 atm at a constant temperature? Do not include
the unit of meașure in your answer.

Breathing is an application of Boyle's law (Figure 10.8). As the diaphragm muscle beneath our lungs
contracts, the pressure inside our lungs decreases, causing air to rush into our mouth and nasal
passages to fill the lungs. When the diaphragm muscle relaxes, it increases the air pressure, causing air to
be expelled from the lungs. A typical lung volume is 3.50 liters (L). Air pressure inside the lungs changes
by approximately 0.040 atm. A sample of air has a volume of 3.50 L at 1.00 atm. But how do we
determine the volume of this air sample if the pressure is changed to 0.960 atm at constant temperature?

A certain flexible weather balloon contains helium gas at a volume of 855 L. Initially, the balloon is at sea level where the temperature is 25C and the barometric pressure is 730 torr. The balloon then rises to an altitude of 6000 ft, where the pressure is 605 torr and the temperature is 15C. What is the change in volume of the balloon as it ascends from sea level to 6000 ft?

Raoul Pictet, the Swiss physicist who first liquefied oxygen, attempted to liquefy hydrogen. He heated potassium formate, KCHO2, with KOH in a closed 2.50-Lvessel. KCHO2(s)+KOH(s)K2CO3(s)+H2(g) If 75.0 g of potassium formate reacts in a 2.50-L vessel, which was initially evacuated, what pressure of hydrogen will be attained when the temperature is finally cooled to 25C?

A 21.4-mL volume of hydrochloric acid reacts completely with a solid sample of MgCO3. The reaction is 2HCl(aq)+MgCO3(s)CO2(g)+H2O(l)+MgCl2(aq) The volume of CO2 formed is 159 mL at 23C and 731 mmHg. What is the molarity of the HCl solution?
Butyl mercaptan, C4H9SH, has a very bad odor and is among the compounds added to natural gas to help detect a leak of otherwise odorless natural gas. In an experiment, you burn 95.0 mg of C4H9SH and collect the product gases (SO2, CO2, and H2O) in a 5.25-L flask at 25 C. What is the total gas pressure in the flask, and what is the partial pressure of each of the product gases?
Many nitrate salts can be decomposed by heating. For example, blue, anhydrous copper(II) nitrate produces the gases nitrogen dioxide and oxygen when heated. In the laboratory, you find that a sample of this salt produced a 0.195-g mixture of gaseous NO2 and O2 with a total pressure of 725 mm Hg at 35 C in a 125-mL flask (and black, solid CuO was left as a residue). What is the average molar mass of the gas mixture? What are the mole fractions of NO2 and O2 in the mixture? What amount of each gas b in the mixture? Do these amounts reflect the relative amounts of NO2 and O2 expected based on the balanced equation? Is it possible that the fact that some NO2 molecules combine to give N2O4 plays a role? Heating copper(II) nitrate produces nitrogen dioxide and oxygen gas and leaves a residue of copper(ll) oxide.
