Say if the concentration of my diluted solution is 0.1920g/L, but it was diluted from 10mL to 250mL so in that case the dilution factor is 250/10 right? so i multiplied 0.1920g/L by 250/10 to get the concentration of my original undiluted solution and I got 4.8. Do I leave the units as it is? So 4.8g/L? If so, what is the reason for this?
