Step 1: Identify the given values for the concentrated and diluted solutions. Concentrated acid: Initial concentration (M_1) = 11.0 M Initial volume (V_1) = ? Diluted acid: Final concentration (M_2) = 0.05 M Final volume (V_2) = 1 dm^3 Step 2: Convert the final volume to cm^3 to match the units in the options. We know that 1 dm^3 = 1000 cm^3. So, V_2 = 1000 cm^3. Step 3: Use the dilution formula. The dilution formula states that the number of moles of solute remains constant before and after dilution: M_1V_1 = M_2V_2 Step 4: Substitute the known values into the formula and solve for V_1. 11.0 M × V_1 = 0.05 M × 1000 cm^3 V_1 = 0.05 M × 1000 cm^311.0 M V_1 = 50 cm^311.0 V_1 ≈ 4.545 cm^3 Step 5: Compare the calculated volume with the given options. The calculated volume is approximately 4.55 cm^3. The options are: A. 5 cm^3 B. (partially visible) C. 550 cm^3 D. 11000 cm^3 Option A, 5 cm^3, is the closest value to the calculated 4.55 cm^3. The final answer is A. 5cm^3. That's 2 down. 3 left today — send the next one.
