Answer:- Concentration of the solution in m/v% is 2.
Solution:- m/v% means mass by volume percentage.
(m/v)% = (mass of solute/volume of solution in mL)100
given, mass of solute = 50. g
volume of solution = 2.5 L = 2500 mL
Let's plug in the values in the formula.
(m/v)% = (50/2500)100 = 2%
The concentration, in [tex]\frac{m}{v} [/tex]% , of a solution prepared by dissolving 50 g NaCl in a total volume of 2.5 l of solution is 2%
Sodium chloride commonly known as salt is an ionic compound with the chemical formula NaCl, represents a 1:1 ratio of sodium and chloride ions. Sodium chloride have the molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na also 60.66 g Cl.
In chemistry, concentration refers to the amount of a substance per defined space. Whereas a solution is a special type of homogeneous mixture composed of two or more substances. The concentration of the solution in [tex]\frac{m}{v} %[/tex] is [tex]2[/tex].
[tex]\frac{m}{v} [/tex]% means mass by volume percentage.
[tex]\frac{m}{v} [/tex]% [tex] = (\frac{mass of solute}{volume of solution in ml})*100[/tex]
Given the mass of solute [tex]= 50g[/tex]
Volume of solution [tex]= 2.5 l = 2500 ml[/tex]
Put in the formula:
[tex]\frac{m}{v} [/tex]% [tex] = \frac{50}{2500} *100 = 2%[/tex]
Therefore the concentration, in [tex]\frac{m}{v} %[/tex] , of a solution prepared by dissolving 50 g NaCl in a total volume of 2.5 l of solution is 2%
