Q9. Show the set-up using words for the calculation of the mass of the H2O2 solution transferred to the flask. Then show the calculation using your data and record in Table 2.
Table 2. Percentage Composition of H202 Solution Temperature of Collected Gas Vapor pressure of H20 in 10 mL cylinder Pressure of dry O2gas Volume of O2gas Moles of O2gas Moles of H202that reacted Mass of H202 Mass of H202 solution transferredto flask Percent H202 by mass in solution Class Mean % H:02 (X) Number of trials in dass data (A) Standard deviation for class data (s) Trial 2 20.2 deg, in c 0.02776 mL 24.0 deg. in C 0.00947 mL 1.001 atm 0.0910 L 0.00398 mole 0.00756 mole 02atm 0.0980 L 0.00404 mL 0.00808 mole 0.275 0.257 2.68% 2.84%Explanation / Answer
Class Mean % H2O2 = 2.76%
Number of trials in data class = 2
Standard deviation for class data = 0.1131
