Document Summary
If you need more space, use the back of the preceeding page and clearly indicate the question number to be graded. R = 0. 08206 l atm/mol k h = 6. 626 x 10-34 joule s and c = 2. 998 x 108 m/s. The equilibrium vapor pressure of water at 28. 0 c is 28. 3 mm hg. 2. (3 marks) a certain gas x is of unknown molecular mass. Under certain conditions of temperature and pressure this gas effuses through a pinhole at a rate of 16. 60 ml in 10 minutes. At the same temperature and pressure argon effuses through the same pinhole at a rate of 15. 0 ml in 5 minutes. 3. (5 marks) a sample of a sulfide of a metal m, (formula mxsy), is submitted to analysis to identify the metal. The sulfur in the sample is recovered as 120 ml of 0. 250 m na2s solution.
