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

A tank originally contains 500 L of water with a salt concentration of 2 grams per liter. Water with a concentration of 1 gram/liter is then poured into the tank at a rate of 3 L/min and the well stirred mixture is allowed to flow out of the tank at the same rate. a) Find a formula for Q(t), the quantity of salt in the tank after t minutes. b) Find the limiting quantity of salt in the tank as t → co
