Which solution could you prepare by dilution?
A. 400 milliliters of 2.50 molar solution from a 2.00 molar stock solution
B. 600 milliliters of 3.00 molar solution from a 2.50 molar stock solution
C. 700 milliliters of 4.50 molar solution from a 3.00 molar stock solution
D. 900 milliliters of 3.50 molar solution from a 4.50 molar stock solution
Please help me understand this question. :)

Best ResponseYou've already chosen the best response.2hint: when we dilute, the molarity of the prepared solution is lower than the molarity of the stock solution

Best ResponseYou've already chosen the best response.2so, look at each answer choice to see which one has a higher stock solution molarity than the prepared molarity

Best ResponseYou've already chosen the best response.0What's the difference between the molar solution and the molar stock solution? And how do you find the molarity?

Best ResponseYou've already chosen the best response.2ok, maybe I can explain it this way the "stock solution" is a solution with a known concentration, and the "prepared solution" is a new solution that we make by taking part of the stock solution and adding water

Best ResponseYou've already chosen the best response.2so, let's take a look at the first answer choice: A. 400 milliliters of 2.50 molar solution from a 2.00 molar stock solution this means, we take a 2.00 molar stock solution, and we try to make a new solution that is 400 ml and 2.50 molar now, going by the rule I stated earlier, the stock solution molarity has to be higher than the new solution 2.00 molar stock is less than 2.50 molar solution so A cannot be our answer
