Respuesta :
The concentration of dye in the diluted solution is 120.
Calculation of concentration:
Since 3 ml of a 400 mg/L solution of a dye is diluted with enough water to give a total volume of 10 mL
So, here the concentration of dye should be
= 3ml of 400
= 120
Simply we multiply the 3 ml with 400 mg/L solution so that the concentration of the dye could come.
Hence, we can conclude that The concentration of dye in the diluted solution is 120.
