51. A2.50-L container isfilled with 175gargon. a. If thepressure is 10.0atm, what isthe temperature? b. If thetemperature is225 K,what isthepressure? 52. Aperson accidentally swallows adrop ofliquid oxygen, O 2 (1), which has adensity of 1.149 g/mL. Assuming the drop has a volume of 0.050 ml., what volume ofgas will be produced in theperson's stomach atbody temperature (37°C) andapressure of 1.0atm? 53. Agas sample containing 1.50mol at 2SOC exerts apressure of 400. torr. Some gasis added tothesame container andthetem- perature isincreased to50. o C. If thepressure increases to800. torr, how many moles ofgas were added to the container? As- sume aconstant-volume container. 54. Abicycle tire isfilled with airtoapressure of75.psi atatem- perature of 19°C. Riding the bike on asphalt on ahot day in- creases thetemperature ofthetireto58°C.Thevolume ofthetire increases by4.0%. What isthenewpressure inthebicycle tire? 55. Consider twoseparate gascontainers atthefollowing conditions: Container A Container B Contents: S02(g) Pressure = P A Moles ofgas = 1.0mol Volume = 1.0L Temperature = 7°C Contents: unknown gas Pressure = P B Moles ofgas = 2.0mol Volume = 2.0L Temperature = 287°C How is the pressure in container B related to the pressure in container A?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
