6. A mass of 135 g of an element is known to contain 3.01 × 1024 atoms. What is the element? 7. A young male adult takes in about 0.0005 m3 of fresh air during a normal breath. Fresh air contains approximately 21 % oxygen. Assuming that the pressure in the lungs is 100000 Pa, and air is an ideal gas at a temperature of 310 K, what is the number of oxygen molecules in a normal breath?
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 ]
An adult breathes in a volume of 1.9 x10-4 m3 each breath. Assume lung pressure is 1x105 Pa and air is ideal gas at 336 K. How many moles are breathed in? Give your answer to two decimal places.
An automobile tire has a volume of 1.61 x 10-2 m3 and contains air at a gauge pressure (pressure above atmospheric pressure) of 167 kPa when the temperature is 0.00°C. What is the gauge pressure of the air in the tires when its temperature rises to 28.6°C and its volume increases to 1.69 x 10-2 m3? Assume atmospheric pressure is 1.01 x 105 Pa.

RC 200 Cardiopulmonary Pathology SOAP Assignment #4 Case Study: Tuberculosis Name:___________________________________ Date:___________________________________________ ADMITTING HISTORY A 58-year-old Caucasian man was well known and liked by the staff at the Samaritan Shelter for the Homeless. The social workers at the shelter had spent a great deal of time and resources working with the man on a number of areas, including his alcohol addiction. Their records showed that they had not seen him for about 6 months. When they last had seen him,...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
