Answer:

concentration of the solution in mass by mass percent is 12.5%

concentration of the solution in mass by volume percent is 1.999....%

Explanation:

mass by mass percent = mass of solute( in gm) /mass of solution( in gm) × by 100

(m/m) % = 60/480×100

(m/m) % = 12.5 %

mass by volume percent = mass of solute (in gm)/ volume of solution ( in ml) * 100

(m/v) % = 60/550×100

(m/v) % = 1.9999..... %
