Calculate the number of moles in the 2.00L volume of air in the lungs of the average person. (Air = 37.0 degrees C) This is how I completed the problem, my book does not contain the answers to our homework so im checking on here to make sure my answer is correct... If not what is the real answer and how did you obtain it? P=1.01E+5 k=1.38E-23J/k T=310K V=2.00L N=PV/kT N=(1.01E+5)(2.00L)/(1.38E-23)(310K) =4.78E-21 Moles
How many moles of air are in the lungs of a average person with a total lung capacity of 3.8 L? Assume that the person is at 1.0 atm pressure and has a normal body temperature of 37 C
Question 8 of 11 > A boy with pneumonia has lungs with a volume of 1.7 L that fill with 0.070 mol of air when he inhales. When he exhales, his lung volume decreases to 1.3 L. Enter the number of moles of gas that remain in his lungs after he exhales. Assume constant temperature and pressure. n = mol
A volume of 2.8 L of air at 36°C is expelled from the lungs into cold surroundings at 0.3°C. What volume does the expelled air occupy at this temperature? The pressure and the number of gas particles do not change. Answer in L
1))))A person’s lungs might hold 6.0 x 10-3 m3 of air at body temperature (37 0C) and atmospheric pressure (101 kPa). Given that air is 21% oxygen (O2), find the number of O2 molecules in the lungs ans: 2.97 x 1022 2)) If the person takes a particularly deep breath, so that the lungs hold a total of 1.5 x 1023 molecules, what is the new volume of the lungs? [Answer: 6.35 x 10-3 m3 ]
A sample containing 1.90 moles of Ne gas has an initial volume of 7.50 L . What is the final volume of the gas, in liters, when each of the following changes occurs in the quantity of the gas at constant pressure and temperature? Part A A leak allows one-half of the Ne atoms to escape. _____L Part B A sample of 4.00 moles of Ne is added to the 1.90 moles of Ne gas in the container. ____L Part...
Problem 17.5 After emptying her lungs, a person inhales 4.0 L of air at 2.0 ∘C and holds her breath. Part A How much does the volume of the air increase as it warms to her body temperature of 36 ∘C ? Express your answer using two significant figures.
What number of moles are in a gas sample with the following data? Volume -5.19 L Temperature - 37.0°C Pressure: 0.985 atm 0.153 mol 0.201 mol 23. 3 mol 128 mol
The average person takes 500mL of air into the lungs with each normal inhalation, which corresponds to aproximately 1x10^22 molecules of air. Calculate the number of molecules of air inhaled by a person with a respiratoy problem who takes in only 350mL of air with each breath. Assume constant pressure and temperature.
Starting with 22.5 moles of O2 in a bottle, calculate the volume of Oz the bottle could deliver to a climber at an altitude where the temperature is - 38.0°C and the atmospheric pressure is 0.387 atm. L
