35ml of active ingredient is mixed with distilled water to total 300ml. What is the final concentration (v/v)? ________
To find the final concentration (v/v), you need to divide the volume of the active ingredient by the total volume of the solution and then multiply by 100.
In this case, the volume of the active ingredient is 35ml and the total volume of the solution is 300ml.
The formula for calculating concentration (v/v) is:
Concentration (v/v) = (Volume of Active Ingredient / Total Volume of Solution) * 100
Plugging in the values:
Concentration (v/v) = (35ml / 300ml) * 100
Calculating the value:
Concentration (v/v) = 0.1167 * 100
Concentration (v/v) = 11.67%
Therefore, the final concentration of the solution is 11.67% (v/v).
