    \[\frac{ 3.255g }{ mL }=\frac{ 3.255kg }{ L }\] 1000 milligrams=1 grams 1000 grams= 1 kilograms.

    The whole process would have to be in conversion?

    So what is the unit for density?

    d=m/v so the unit of density is the (unit of m)/(unit of v) M is mass V is volume What are the units for mass and volume?

    Yes that works. So density is g/mL or kg/L

    Can you answer this? The whole process would have to be in conversion (dimensional analysis) ?

    Does the whole process need to be like this? \[\frac{ ? }{ ? } \times \frac{ ? }{ ? } \times \frac{ ? }{ ? }\] Its a just a yes or no.

    Ok, you start with given and make the units cancel until you get Liters by itself. Similar to what I did earlier. Since you wouldnt mind trying, show me your dimensional analysis, then I can show you mines.

    If you are given unit1 and want to find unit 3 use this \[\frac{ Unit1 }{ 1} \times \frac{ Unit 2 }{ Unit1 } \times \frac{ Unit 3}{ Unit2 }\]

    Notice how unit 1 and unit cancels out?

    It is supposed to be 123000 mg /1 at the beginning. That is the given unit.

    \[\frac{ 1236000mg }{ 1 } \times \frac{ 0.000001kg }{ 1mg } \times \frac{ 1000g }{ 1kg }\times \frac{ 1mL }{ 3.255 g } \times \frac{ 0.001L }{ 1mL }\]

    3.255 g/mL can be switched as mL/3.255g

    In my opinion without using the dimensional analysis (factor), it is shorter.

    Glad to help! I have to go out for dinner now. If you still need help, PM me like 2-3 hours. Good luck on the rest!
