mililiters
You would use Volume.
No - kilograms are units of weight - not volume !
You fill up water ina beaker, measure the volume of the water as it originally was, then drop in an irregulary-shaped object, measure that volume, and subtrect the two. The difference is the volume of the object.

Which lab tool might you use to measure the volume of a liquid?
The answer is a graduated cylinder.
In the SI system you would use the cubic metre.
To measure volume
There are three ways to measure volume. If you are measuring a liquid, you need a graduated cyliner. If you are measuring the volume of a regular solid, you need a ruler to measure length, width, and height. You would then use the formula V=LxWxH. The third way to measure volume is to use displacement to find the volume of an irregular solid. You would put a certain amount of water in a graduated cylinder, write the starting amount down. Add the irregular solid to the graduated cylinder. Record the ending amount of liquid and subtract the ending amount minus the starting amount.
I would place it in a container full of liquid after measuring the liquid. I would measure the amount of liquid displaced by the object. That amount is equal to the volume of the irregular object if it is fully submerged in the liquid.
The formula of volume
In a modern lab, you would use a digital scale to measure mass. Historically, balances and spring scales were used.
graduated cylinder
gramsWHAT
A graduated cylinder is used for measuring the Volume of different things such as irregular objects. It uses the unit ml. It has a miniskus FYI that is when you use water and if you look closely you can see it curve at the top. You measure the miniskus a the bottom of the Curve. Also to find the Volume of an irregular object you first measure the water (starting volume) then place the Object in it and you will have your ending volume. then subtrct the difference from the starting volume and the ending and you will have your volume in ml.
1. Measure the dimensions of the object 2. Calculate the volume, in cm3 3. Weigh the object, in g 4. The density is the ratio between the mass and the volume, in g/cm3. For small objects you can use special densimetric balances.
