I am completely stuck on this one. I understand about the densities and putting the lightest on top and heaviest on bottom, but what am I entering as a code? Is it the densities of each one in order? If so, how many digits do I use for each? Or have I missed the boat completely here?

I’m stuck
Searched online for equivalent densities but it doesn’t seem to work either forwards or backwards. It is a numerical code right?
You are on the right track. Double check that you have the right sequence.
[Spoiler]Start from the top (lightest) to bottom (densest). Google Images has some great examples of the experiment to help guide you...[/spoiler]
What units are you using? How many significant figures? What separators (if any) are you using?

The number on each test tube.
