Question 1144706: A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is 65% salt and Solution B is 90% salt. She wants to obtain 70 ounces of a mixture that is 80% salt. How many ounces of each solution should she use? Found 2 solutions by Alan3354, ikleyn:Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is 65% salt and Solution B is 90% salt. She wants to obtain 70 ounces of a mixture that is 80% salt. How many ounces of each solution should she use?
------------
Assuming there is some compound that can be 90%, or even 65%, in some solvent, which I doubt:
"Salt" is not necessarily NaCl. There are a lot of salts.
---------------
A + B = 70 --- total solution
65A + 90B = 70*80 ---- total salt
---------
etc
The salt solution CAN NOT have concentration higher than 28%.
After that the solution becomes SATURATED.
To know this fact from SCIENCE is MUCH MORE IMPORTANT thing than to "solve" mechanically problems,
posed incorrectly, without understanding the subject.
