The researcher needs to add 20 ml of 8% solution and 10 ml of 17% solution to make a 11% solution
<h3>What do you mean by Concentration ?</h3>Concentration is the measure of the mass of solute in certain volume of solution.
The parameters useful in measuring concentration is Molarity , Normality , Molality etc.
It is given that concentration of saline solutions with concentrations of 8% and 17%.
A mixture of 11% 30 ml concentration solution has to be made
The formula for mixing mixtures is given by
Here m₁ and m₂ represents the concentration and x₁ and x₂ represents the volume of solution added x₁ = x and x₂ 30-x
M = ( 8 * x +(17*(30-x))/(30)
30*11 = 8x +510 -17x
330 = -9x +510
9x = 180
x =20ml
Therefore the researcher needs to add 20 ml of 8% solution and 10 ml of 17% solution to make a 11% solution.
