Question

In questions 5 and 6, assume 1.00 mol of any gas occupies 22.40 L at standard temperature and pressure (STP). 5. What volume of oxygen, at STP, is required to burn exactly 1.48 L of propane ($C_3H_8$), according to the reaction below? $C_3H_8(g) + 5 O_2(g) \rightarrow 3 CO_2(g) + 4 H_2O(g)$ 6. What volume of nitrogen gas is obtained when 2.39 g of sodium azide ($NaN_3$) decomposes at STP? $2 NaN_3(s) \rightarrow 2 Na(s) + 3 N_2(g)$ 7. How much faster does $H_2$ gas escape through a porous container than Xe? 8. Calculate the volume of a tube, given that pressure inside the tube is 0.0021 atm, its temperature is 56.2 $^\circ$C, and it contains 4.91 mg of fluorine gas.
