ited .doc C The stopcock connecting a 2.00 L bulb containing nitrogen gas at a pressure of 636 mm Hg, and a 2.00 L bulb containing methane gas at a pressure of 446 mm Hg, is opened and the gases are allowed to mix. Assuming that the temperature remains constant, what is the final pressure in the system?

Finding vapor pressure / Partial pressure and moles using the Data collection

Compare, at the same temperature and pressure, equal volumes of H2 and O2 as to the following:   massmass O2 = (insert answer) times mass of H2    density density O2 =(insert answer) times the density of H2

my fault. I am talking about question 30.     I am guessing that when looking at Density questions of gases,  D= m/v   Since ideal gases have no volume, is it true that the volume is assumed always to be the container?  # 30 is tough

Answer both 1 &2 .if u answer only 1st quesion I will downvote

Test Tube #1: Pure KCIO3 Sample 1. Determine the weight of KCIO3 heated. 2. Determine the weight of oxygen gas lost using the constant weight obtained from repeated heatings. 3. Based on the values obtained above, determine the experimental percent of oxygen in KCIO3 HINT: Percentage is defined as the "part" of interest divided by the total times 100. Determine the theoretical percent oxygen present in KCIO3 using stoichiometry. 4. 5. Based on the values obtained from #3 and #4, determine the percent error of percent oxygen.

Richards and Willard determined the molar mass of lithium and collected the following data.   Experiment Molar Mass, g/mol 1 6.9391 2 6.9407 3 6.9409 4 6.9399 5 6.9407 6 6.9391 7 6.9406   a. Find the mean molar mass determined by these workers. b. Find the median molar mass. c. Assuming that the currently accepted value for the molar mass of lithium is the true value (state your reference), calculate the absolute error and the percent relative error of the mean value determined by Richards and Willard.
