Here are the calculations for the given problem. a) Calculate the: i) Average volume of solution W used The table for burette readings (Table 1) is empty. To calculate the average volume of solution W used, experimental data from the titration (final and initial burette readings) is required. Since this data is not provided, the average volume cannot be calculated. ii) Concentration of solution W Solution W is prepared by diluting 75 cm^3 of solution K (1 M H_2SO_4) to 250 cm^3. Step 1: Convert the volumes to dm^3. Initial volume of solution K (V_K) = 75 cm^3 = (75)/(1000) dm^3 = 0.075 dm^3 Final volume of solution W (V_W) = 250 cm^3 = (250)/(1000) dm^3 = 0.250 dm^3 Step 2: Use the dilution formula C_1V_1 = C_2V_2 to find the concentration of solution W (C_W). Here, C_K V_K = C_W V_W. (1 mol/dm^3) × (0.075 dm^3) = C_W × (0.250 dm^3) Step 3: Solve for C_W. C_W = 1 mol/dm^3 × 0.075 dm^30.250 dm^3 C_W = (0.075)/(0.250) mol/dm^3 C_W = 0.300 mol/dm^3 Last free one today — make it count tomorrow, or type /upgrade for unlimited.
