During a breath, the average human lung expands by about 0.50 L. If this expansion occurs against an external pressure of 1.0 atm, how much work (in J) is done during the expansion? Express your answer using two significant figures.
4.0 101 56 How many moles of gases are contained in a human breath that takes in 0.50 L of air at 1.0 atm pressure and 37 °C? PV A 0.165 mol B 2.0 moł D 2.1 mol 1.2 mol NT
This question has multiple parts. Work all the parts to get the most points. The average lung capacity of a human is 59 L. How many moles of air are in your lungs when you are in the following situations? Asume air behaves ideally and has an average moler mass of 29.0 g/mol. At sea level (T-298 K, P -...
This question has multiple parts. Work all the parts to get the most points. a The average lung capacity of a human is 6.0 L. How many moles of air are in your lungs when you are in the following situations? Assume air behaves ideally and has an average molar mass of 29.0 g/mol. At sea level (T = 298...
How many joules of net work does this person's lung do during one complete breath? Express your answer to three significant figures and include the appropriate units Constants Work Done by the Lungs. The graph (Figure 1) shows a pv diagram of the air in a human lung when a person is Inhaling and then esthaling a deep breath Such...
2. The air we breathe contains approximately 21.0 mol% oxygen. The average person breathes 0.50 L of air per breath a. If the atmospheric pressure is 745 mmHg, what is the partial pressure of oxygen in atmospheres? b. On a warm April day in Indiana, the air is 26.85 °C, how many moles of oxygen are inhaled in one breath?...
A normal breath takes in about 1.0 L of air. Assuming that air has an average molar mass of 28.8 g, and that its density is 0.97 g/L. how many molecules of air do you take in with each breath? 2.0 times 10^22 2.2 x 10^22 5.8 times 10^23 1.7 times 10^25 1.8 times 10^25
n = 40.304 24.30416 moleaner haunt 17. Anna exhaled air containing CO2 at a pressure of 27.0 torr. The capacity of a human lung is about 3.00 L. Body temperature is 36.5°C. a) (5 pts) Convert the pressure to atm. b) (5 pts) Convert the temperature to Kelvin scale. c) (8 pts) Calculate the mass of CO2 in a lung...
If you have ever hiked or climbed to high altitudes in the mountains, you surely have noticed how short of breath you get. This occurs because the air is thinner, so each breath contains fewer O2 molecules than at sea level. At the top o Mt. Everest, the pressure is only atm Air contains 21.0% O2 and 78.0% N2, and...
(1 point) Consider modeling the concentration of a chemical in a lung using the table below. 1 if the starting concentration is co 0.1 mmol/L Fill in the missing values and calculate the concentration at time t (millimoles per liter). Suppose the volume of the lung is V 2.5 liters, the volume of air inhaled and exhaled in each breath...
