Dry ice is solid carbon dioxide; it vaporizes at room temperature and normal pressures to the gas. Suppose you put 26.6 g of dry ice in a vessel fitted with a piston, and it vaporizes completely to the gas, pushing the piston upward until its pressure and temperature equal those of the surrounding atmosphere at 21.7 °C and 751 mm Hg. Calculate the work done by the gas in expanding against the atmosphere. Neglect the volume of the solid carbon dioxide, which is very small in comparison to the volume of the gas phase.
Calculate the concentration of an pilocarpine solution with a pH = 9.34. The Kb of pilocarpine is 7.41x10-8 i need to know the steps to do problems like this one, if the steps can be simplified that would be great, thanks a lot.
