LOMBO ONO Data Part I. The effect of gas volume on pressure PRESSURE (atm) VOLUME (L) 240 29.0 ZA 0.846 025 D. C70 0.550 Sketch the graphs of P vs. V and P vs. I/V. Label axes. Also record the best-fit equation for Pvs. 1/V. Y+0.363x +6.005 R = 0.9935 EP Analysis Questions Calculate the volume at which your syringe would have reached 1.75 atm, thus popping the safety valve inside the MicroLab box. (You can calculate this using any one of your seven P-V data sets, or with the best-fit equation from the graph.) 1.25 = 6.6367x +0.005 1.745 -0.0303 x = 59.16 Assuming that the syringe was completely filled with nitrogen and the room was 21°C, calcu. late (a) the number of nitrogen molecules inside the syringe and hose and (b) the mass of those molecules. Again, any of your seven P-V data sets can be used. (24)(6.024)

Answer 1

O p =1.75 atm, v=7 PV= constant 1.75 XV. = 1.336 x 24 me =) V=18-32 ml PV= * N ko'TI N = 1.336 atm, xau ml 1.38 x 1023 J y a guk (a) = 1.336 x 1013x10sxauxio-lam? 1.38 x 1023 yagy a N = 8 8 10 20 20 N=loof nitrogen molecules: w = NX to 28 u -27 = 8x10 20 x 28 x 1067377x10 kg = 3.75 X 10 kg = 0.0375 gm.
