Answer 2

Given - v/v = 3%

The volume of bottle = 400 ml

Find - Volume of solute in bottle

Solution - The volume by volume percentage indicates the volume of solute in a volume of solution. Thus, as per the information, 100 millilitres of solution will have 3 millilitres of hydrogen peroxide.

As 100 millilitres will have 3 millilitres,

400 millilitres will have = 3/100*400

400 millilitres will have 12 millilitres.

Hence, the bottle will have 12 millilitres of agua oxigenada.
