The molarity of a NaOH solution that is prepared by mixing 50.0 ml is <u>0.14 M</u>
Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.
<u>Calculation:-</u>
C₁ = 0.350 M
V₁ = 50 ml = 0.05 L
C₂ = ?
V₂ = 125 ml = 0.125 L
C₁V₁ = C₂V₂
C₂ = C₁V₁ / V₂
= 0.350 × 0.05 / 0.125
= <u>0.14 M</u>

The concentration of a substance is the quantity of solute found in a given amount of solution. Concentrations are normally expressed in terms of molarity, defined because of the variety of moles of solute in 1 L of Solution.
The Concentration of an answer is a measure of the quantity of solute that has been dissolved in a given amount of solvent or answer. A concentrated answer is one that has a rather huge quantity of dissolved solute.

Answer: 20 gallons of 16% and 8 gallons of 23% solution is usedfor 28 gallons of the 18 % solution.
Explanation:
According to the dilution law,
where,
= concentration of ist disinfectant solution = 16 %
= volume of pure acid solution = x gallons
= concentration of another disinfectant solution= 23%
= volume of another acid solution= (28-x) gallons
= concentration of resulting disinfectant solution = 18 %
= volume of resulting acid solution = 28 gallons
![x=20galllons](https://tex.z-dn.net/?f=x%3D20galllons)
(28-x) = (28-20) = 8 gallons
Thus 20 gallons of 16% and 8 gallons of 23% solution is usedfor 28 gallons of the 18 % solution.
