Here is how I mix liquid [...]/Diazepam with water to create my daily solution. I make a large batch that I later draw my doses from because it is much easier than trying to mix one dose at a time when I need it.
What I am writing in this post is an example. You could certainly make a larger batch with a larger container as long as you follow the ratio of 1 ml of liquid [...] for every 9 ml of water. As [...] has explained, this makes the math easier while tapering and provides you a solution with a lower concentration of [...], which allows you taper daily by a smaller amount. This creates for an easier taper.
I use a 10 ML syringe that I bought in a batch from Amazon:

I use the 10 ML syringe to measure out 10 ML of water and I spray that into the bottom of the jar. I do that twice so that I have 20 ml of water at the bottom of the jar. This prevents any of the liquid Diazepam from sticking to the bottom of the jar--even though it would be an imperceiveable amount if any.
I then use the same syringe to draw out 10 mg of liquid Diazepam and spray it into the jar with the 20 ml of water. I do this again and draw an additional 10 ml of liquid [...] and spray it into the second jar with the water.
The jar now has 20 ml of water and 20 ml of liquid diazepam in it.
I then use the same syringe to draw 10 ml of water and spray it into the jar. I repeat this 14 times so that the jar now has a total of 180 ml of water and 20 ml of liquid diazepam in it.
By drawing the water into the same syringe after I used it to draw the liquid diazepam and spraying it into the jar, I make sure to wash out any of the liquid Diazepam that might have stuck in the syringe--although none is visible to me.
I now have a jar with 200 ml of solution with the water at a 9-1 ratio with the liquid diazepam. At this point I close and shake the jar. I also shake it every day before drawing my daily dose.
Another thing that I do is pour a bunch of the liquid diazepam out of its container into a glass jar and use that to draw from to make my mixture.
I do this for two reasons:
1. It is very hard and awkward to draw the liquid diazepam out of its container while it is much easier to do so out of a jar since the jar has a wider top to get the syringe into and is smaller and easier to work with.
2. I am afraid that I might wind up dropping or spilling the liquid diazepam container if I am trying to tilt it to draw liquid out of it with a syringe.
When taking my dose, I shake the jar with the mixture, open it, and use the 10 ml syringe to draw out 10 ml of the mixture. Then I spray it down my throat.
Remember, Each 10 ML of the liquid I mixed consists of 9 ml of water and 1 Ml of liquid [...]/Diazepam.
I take as many 10 ml doses as I need for each mg of [...] that I take.
The 10 ML syringes have 4 markings between each individual ml mark to allow you to measure .2 of each ml. This allows you to gradually taper.
You might also want a 1 ML syringe to make finer cuts:
