Let's assume Gabe needs x liters of the 20% solution.
Since he needs a total of 50 liters, he will need 50 - x liters of the 70% solution.
To find the amount of acid in the final solution, we can use the equation:
0.2x + 0.7(50 - x) = 0.6(50)
0.2x + 35 - 0.7x = 30
-0.5x = -5
x = -5 / -0.5
x = 10
Therefore, Gabe needs 10 liters of the 20% solution.
Gabe Amodeo, a nuclear physicist, needs 50 liters of a 60 acid solution. He currently has a 20 solution and a 70 solution. How many liters of each does he need to make the needed 50 liters of 60 acid solutions
Gabe needs

He also needs
enter your response here liters of the 70% solution.
enter your response here liters of the 70% solution.
Since Gabe needs a total of 50 liters and already has 10 liters of the 20% solution, he will need 50 - 10 = 40 liters of the 70% solution.
