23. Determine the theoretical yield and the percent yield if 21.8 g of K CO, is produced from reacting 27.9 g KO2 with 29.0 L of CO2 (at STP). The molar mass of KO2 71.10 g/mol and K,CO 138.21 g/mol 4 KO2(s) + 2 CO2(g) â 2 K2CO3(s) + 3 02(g) 24. W hich of the following gas samples would be most likely to behave ideally under the stated conditions? A. Ar at STP B. CO at 200 atm and 25°C C. SO2 at 2 atm and 200 K D. N2 at 1 atm and -170°C E. 02 at 10 atm and-100 °C 25. The rate of effusion of oxygen to an unknown gas is 0.935. What is the other gas? 26. A sample of Cl2 effuses in 350 s. How long will the same size sample of N2 take to effuse? 27. If NO and NH, are allowed to effuse through a porous membrane under identical conditions, the rate of effusion for NH, will be times that of NO. 28. Calculate the root mean square velocity of CO2 molecules at 25°C
