In a lab a 30% acid solution is being mixed with a 5% solution to create a 10% acid solution. What is the ratio of the amount of the 30% solution to the amount of the 5% solution used to create the 10% solution

Answer:

1:4

Step-by-step explanation:

  • 30% solution = x
  • 5% solution  = y

then

  • 10% solution = x + y

Amount of acid:

  • 0.3x + 0.05y = 0.1(x+y)
  • 0.3x + 0.05y = 0.1x + 0.1y
  • 0.2x = 0.05y
  • 20x = 5y
  • 4x = y
  • x/y = 1/4

So the ratio of 30% solution to the 5% solution is 1:4
