See the illustration. If the contents of the two test tubes are poured into a third test tube, how much solution will the third test tube contain? (ml means milliliters.) (______) mL. Which is the best estimate of the concentration of the solution in the third test tube? 30% acid solution 25% acid solution 35% acid solution 45% acid solution

Solution

a)

third test tube volume = x mL + y mL

= (x+y) mL

b)

when both are mixed,acid concentration will be graeter than minimum and smaller than maximum.

So concentration will be between 30% and 40 %

Answer:

35% acid solution
