Given conditions ⇒
Mass of the Potassium Chloride = 2.5 g.
Volume of the Potassium Chloride Solution = 50 mL.
∵ Concentration = Mass/Volume
∴ Concentration of the Potassium Chloride in Solution = 2.5/50
= 0.05 g/mL.
∴ Mass-volume Concentration in % = 0.05 × 100
= 5 %
Hope it helps.

Given data :
Mass of Potassium = 2.5 g
Volume of Potassium Chloride = 50 ml
To find : Mass / Volume %
Solution :
Mass / Volume % = 2.5 g / 50 ml * 100
=> 250 g / 50 ml
=> 5 %
Therefore Mass / Volume percentage = 5 %
