Question

A solution contains 95 mL of alcohol in 0.105 L of water . Calculate the volume percentage (v/v)% of the solution . What will be the change in concentration if i) The solution is diluted with 25 mL water ii) 5 mL alcohol is added to it, considering the changes to be made under similar temperature and pressure​

Answer 1

Answer:

For example, to make 70% ethanol from 95% ethanol, take 70 mL of 95% ethanol and add enough water to bring the volume to 95 mL. You will then have 95 mL of 70% ethanol.
