the beakers pictured above, which solution is more concentrated? You can assume both solutic О Вeaker A D Beaker B The concentration is the same in both beakers

How many mL of water should be added to 50.0 mL of a 15.0 M H2SO4 solution to give a final concentration of 0.300 M? A) 950 mL B) 1000 mL C) 2450 mL D) 2500 mL

A 72.0 mL portion of a 1.70 M solution is diluted to a total volume of 288 mL. A 144 mL portion of that solution is diluted by adding 105 mL of water. What is the final concentration? Assume the volumes are additive. concentration: M

To a solution of NaCl, a crystal of NaCl is added and the crystal dissolved. How would you classify the original solution?

In a solution the substance which is being disolved is the

Lisa, a librarian at the Knights of Favonius, is also a great potion maker. She wants to create a potion containing potassium dichromate (K2Cr2O7). The only available solutions in her laboratory are 25.0 mL of 0.650 M solution and 18.0 mL of 0.350 M solution.   What is the concentration of potassium dichromate (in M) when the two solutions are combined? What is its concentration in % w/v? For this potion to have a stronger effect, Lisa wants it to have a concentration of 20.0 % w/v. Can she create it based on combining the available solutions alone? Lisa only settled to produce the lesser potent potion with 10.0 % w/v. How much water will she add (in mL) to achieve this concentration?

21. A 400.0 mL solution contains 15.0 g of ethanol (C₂H,O). What is the concentration (in M) of ethanol? A: 0.814
