Now that you have determined the concentration of the base used to titrate the HCl in the micropipette, and you have recorded the volume of the HCl sample (5.00 mL) and the number of mL of base used, you can calculate the concentration of the HCl solution. Pop up the Data Sheet to get the number of mL of base used to titrate the HCl solution. First calculate the number of moles of base used (be careful about the volume units): moles base = (Vbase) (Mbase) Moles of base mol This is equal to the number of moles of HCl present in the 5.00 mL of HCL delivered to the flask.

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
