Question

what is the molarity of a naoh solution that is prepared by mixing 50.0 ml of 0.350 m naoh with 125 ml of h2o?

Answer 1

The molarity of a NaOH solution that is prepared by mixing 50.0 ml is 0.14 M

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.

Calculation:-

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

   = 0.14 M

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.
