Given mass of urea $= 16\ g$ And,
mass of solution $= 120\ g$
So, Concentration of solution $=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times100$
Concentration of solution $=\frac{16}{120}\times100=13.33\%$
mass of solution $= 120\ g$
So, Concentration of solution $=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times100$
Concentration of solution $=\frac{16}{120}\times100=13.33\%$
