how to find the missing data in Table 1?

Part 1: Getting Ready 1. Obtain 5 pieces of filter paper from your TA. 2. Record the exact stock concentrations of the reactants into Table 2. 3. Obtain one pump (10 mL) of Na2S2O3 in a 50 mL beaker. 4. In a 50 mL beaker, obtain (12.5 mL) of 0.2 MKI. 5. Obtain one pump (12.5 mL) of 0.1 M H₂O₂ in a 50 mL beaker and add 10 drops of 6M HCL. 6. Divide the filter paper into quarters. Part 2: Preparation of Solutions 1. In a 25.00 mL volumetric flask add one pump (12.5 mL) of 0.1M H₂O2, add 10 drops of 6M HCL, and dilute to the mark with RO water. 2. In a 25.00 mL volumetric flask add one pump (12.5 mL) of 0.2M KI and dilute to the mark with RO water. Part 3: Run 1 1. Place your watch glass on top of your white tile. 2. Place a piece of filter paper on top of a watch glass. Label the filter paper with an 'x' to mark the center or target area for your reagents (see Figure 1 on next page). 3. Add the reagents as shown in Table 1 on the target you marked on the filter paper. Your medicine dropper should be no more than an inch from the filter paper. 4. Start the timer as soon as you add the first drop H₂O₂. 5. Record the time when you see the first sight of brown on the filter paper. Repeat steps 1-5 for this run four more times, cleaning the watch glass and using a new filter paper for each trial. 6.
