Ashlynn Stahl Chem. Lab 10/22/19 Boyle’s Law Post Lab 1) Calculate the number of moles of gas in the syringe using data from the graph. There was 4.8x10 -4 . moles of gas in the syringe. 2) Calculate the number of molecules of gas in the syringe using Avagadro’s number and the number of moles you calculated earlier. (Avagadro’s number = 6.02 x 10 23 molecules/mol). 2.9 x 10 20 molecules/mol. How many of those molecules are oxygen? (research the percent of O 2 in the atmosphere and calculate using ratios). x= .21(2.9 x 10 20 molecules/mole) 6.09 X 10 19 of those molecules are oxygen. Calculate the volume for 1 mole using your answer from postlab question 1. Calculate your percent error compared to the standard value for the volume of one mole of gas at STP - 22.4L. (Hint: ) The volume of one mole is 2.08 x 10 -7 . The % error is 2.08 x 10 7 / 22.4 ( 100 )= 1.95% What happens to the molecules in the gas when compressed? What would happen to

When the gas in the syringe is compressed the molecules bounce off the edges of the container more frequently and the presser becomes higher. If the gas was continued being compressed the molecules would be condensed and condensed until it turns into a liquid form. show your data below Table 1 Pressure (kPa) Volume (mL) Pressure (kPa) constant, k 5.8 189.20 1097.36 7.8 146.75 1144.65 9.8 115.86 1135.428 11.8 96.55 1139.29 13.8 80.91 1116.558 15.8 70.10 1107.58 17.8 62.73 1116.594 19.8 57.10 1130.58 Average K 1123.505k k value from graph 2 1173kPa/L/mL *************** % error 4.219% *************** T in K: 295.15K Calculate the number of moles in your syringe (SHOW ALL WORK) n = 4.8 x 10-4...

### 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.
