You are given a concentrated stock solution of 3.0 M sucrose, and you’re asked to do a serial dilution of 1:25, 1:10, and 1:5. What is the final concentration of sucrose (in mM) you achieve after these dilutions. Show your unit conversions step by step

To prepare the solution you would place the solute in a 50.0 ml volumetric flask, and then fill to the mark with water while mixing. This would give a total solution volume of 50.0 ml. The 5.0 solution needs to be diluted to make 10.0 ml of a 2.0% solution. What volume of 5.0% solution should be used? Please answer fast i give you upvote.
