Isopropyl alcohol is mixed with water to produce a 35.0 % (v/v) alcohol solution. How many milliliters of each component are pre
PilotLPTM [1.2K]

229.25 mL of isopropyl alcohol

425.75 mL of water

Explanation:

Knowing that the solution have a 35.0 % (v/v) isopropyl alcohol in water, we can calculate the volume of each component as following.

volume of  isopropyl alcohol = (35/100) × solution volume

volume of  isopropyl alcohol = 0.35 × 655 mL = 229.25 mL

Now, knowing the volume of isopropyl alcohol we can determine the volume of water.

volume of the solution = volume of isopropyl alcohol + volume of water

volume of water = volume of the solution - volume of isopropyl alcohol

volume of water = 655 mL - 229.25 mL = 425.75 mL
