how many ml of water should you add to the 60 ml of concentrated solution to dilute it to a total of 150 ml? concentrated volume + water = dilute volume 60 ml + ? ml = 150 ml
Answer
Explanation:
Step1: Set up the volume - relationship equation
Let the volume of water to be added be $x$ mL. We know that the volume of the concentrated solution plus the volume of water added equals the volume of the dilute solution. So, $60 + x=150$.
Step2: Solve for $x$
Subtract 60 from both sides of the equation: $x = 150 - 60$. $x=90$
Answer:
90 mL
