Pipet (1.0x10^1) mL of a sample solution into a 250.00 mL volumetric flask and dilute to the mark with distilled water. Then, pipet 2 mL of this diluted solution into a 50.00 mL volumetric flask and dilute to the mark with distilled water. What is the dilution factor of the final solution? (Note: keep one decimal in your answer.)

4.84 mL of a dark blue solution with a dye concentration of 15.72 %m/v is diluted to a total volume of 140. mL. What is the new concentration of the solution in units of %m/v? Do not include units in your answer.

5.00 mL of stock solution is diluted to 25.00 mL, producing solution ALPHA. 10.00 mL of solution ALPHA is diluted to 25.00 mL, resulting in solution BETA. 10.00 mL of solution BETA is then diluted to 25.00 mL, producing solution GAMMA. dilution factor for ALPHA from stock solution = 0.167 dilution factor for BETA from ALPHA solution = 0.0476 part c and d?

A lab prepared a solution of sulfuric acid with a volume of 5.0x10-4 m3. The solution is further concentrated to the half of the original volume, which is used to neutralize a potassium hydroxide solution. The potassium hydroxide solution has a volume of 30 mL, contains 30 g water, and has a density of 1.0141 g/cm3. What is the molarity of sulfuric acid in the concentrated solution? (The final answer keeps 4 digits after decimal. Please do NOT use scientific notation.)

A standard solution was prepared by dissolving 0.2436 g of tin (II) chloride (SnCl2) in distilled water. The solution was diluted to a total volume of 100 mL. A 2-mL portion of this standard was then diluted to a 50-mL final volume to create the desired solution. What is the final concentration of the solution in ppm?
