- How many moles of chlorine gas at 120. °C and 33.3 atm would occupy a vessel of 39.0 L?arrow_forwardHow many liters of dry hydrogen gas, measured at 798 mmHg and 21C, will be released by the decomposition of 230 mL of H20 at 1.42atm and 30C? 2 H20 (g) → 2 H2 (g) + O2 (g) Answer to 3 decimal places. Your Answer: Answer unitsarrow_forwardAn adult takes about 12 breaths per minute, inhaling roughly 500 mL of air with each breath. The molar compositions of the inspired and expired gases are as follows: Species Inspired Gas (%) Expired Gas (%)O2 20.6 15.1CO2 0.0 3.7N2 77.4 75.0H2O 2.0 6.2The inspired gas is at 24°C and 1 atm, and the expired gas is at body temperature and pressure (37°C and 1 atm). Nitrogen is not transported into or out of the blood in the lungs. All nitrogen inhaled is exhaled. 1. Calculate the masses of O2, CO2, and H2O transferred from the pulmonary gases to the blood or vice versa (specify which) per minute. 2. Calculate the volume of air exhaled per milliliter inhaled. 3. At what rate (g/min) is this individual losing weight by merely breathing?arrow_forward
- A cylinder of gas at room temperature (20 degrees Celsius) has a pressure P1. To what temperature in degrees Celsius would the temperature have to be increased for the pressure to be 1.2p1?arrow_forwardA quantity of gas in a piston cylinder had a volume of 0.539 m^3 and a pressure of 200 Pa. the piston compresses the gas to 0.222 m^3 in an isothermal (constant-temperature) process. What is the final pressure of the gas?arrow_forwardIn 2011, researchers showed that hypochlorous acid (HClO) generated by white blood cells kills bacteria. Calculate the percent dissociation of (a) 0.40 M HClO; (b) 0.035 M HClO (Ka = 2.9x10-8).arrow_forward
- At 25.0 °C the Henry's Law constant for dinitrogen monoxide (N,0) gas in water is 0.025 M/atm. Calculate the mass in grams of N,0 gas that can be dissolved in 450. mL of water at 25.0 °C and a N,0 partial pressure of 1.31 atm. Be sure your answer has the correct number of significant digits. ?arrow_forwardDetermine and report the pressure of collected hydrogen gas in atmospheres. Report this result to one more digit than allowed by applying the rules of significant figures. (1 atm = 760 mm Hg, an exact conversion factor.) Determine the moles of hydrogen collected by substituting the appropriate quantities into the ideal gas equation and solving. Report this result to one more digit than allowed by applying the rules of significant figures. Notes: the gas temperature is the same as the listed temperature; R = 0.082057 L-atm/mol-K. Be mindful of units. Determine the experimental atomic mass of Cu. Round this result to the correct number of significant figures. Determine the percent relative error (= ????????????−?h????????? ? 100). The molar mass of Cu is 63.546 g/mol. Mass of copper before electrolysis 6.008 g Mass of copper after electrolysis 5.860 g Volume of H2 collected 58.9 mL Pressure of H2, PH2 720.8 mm Hg Temperature 24.0 oCarrow_forwardA mouse is placed in a sealed chamber with air at 754.0 torr. This chamber is equipped with enough solid KOH to absorb any CO2 and H2O produced by the mouse. The gas volume in this chamber is measured to be exactly 2.00 L, the temperature is held constant at 295 K. After two hours the pressure inside the bottle falls to 717.4 torr. What mass of oxygen has the mouse consumed?arrow_forward
- Determine the concentrations (in mole fraction) of all species in the exhaust from the incomplete combustion (90% combustion) of butane (C4H10). Assume 50% excess air with respect to complete combustion is the source for the oxygen. Air composition is 79 mol% N2 and 21 mol% O2.arrow_forwardNicotine, an alkaloid in the nightshade family of plants that is mainly responsible for the addictive nature of cigarettes, contains 74.02% C, 8.710% H, and 17.27% N. If 40.57 g of nicotine contains 0.2500 mol nicotine, what is the molecular formula?arrow_forwardA student ran the following reaction in the laboratory at 759 K: N2(g) + 3H2(g) = 2NH3(g) When she introduced 3.13×10-2 moles of N2(g) and 6.00x102 moles of H2(g) into a 1.00 liter container, she found the equilibrium concentration of NH3(g) to be 6.84×10-4 M.
