What is the concentration, in m/v%, of a solution prepared by dissolving 50. g nacl in a total volume of 2.5 l of solution?

- 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%

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

the correct answer would be d. hope this !
