a) At the end of the reaction, the temperature was 21.5 oC (294.65 K), 99.2 mL of gas were formed, and the pressure was 1.00 atm in the gas syringe. The Gas Constant has a value of 0.08206 L atm/ (mol K) (Pay attention to these units!!!). How many moles of Mg reacted?

b) What Molar Mass did you calculate for Mg?

The ideal gas law PV=nRT relates pressure P, volume V, temperature T, and number of moles of a gas, n. The gas constant Requals 0.08206 L⋅atm/(K⋅mol) or 8.3145 J/(K⋅mol). The equation can be rearranged as follows to solve for n: n=PVRT This equation is useful when dealing with gaseous reactions because stoichiometric calculations involve mole ratios.

n this exercise, weighed samples of a solid unknown containing NaCl and NaHCO3 react with hydrochloric acid. The volume of the CO2 liberated by the reaction in the gas phase is measured with a gas collection syringe. From the volume we can calculate the number of moles of CO2 in the gas phase using the ideal gas approximation. Since the CO2 is generated in an aqueous environment (aqueous HCl), some CO2 will dissolve in the liquid phase. The amount of...
