What instrument measures liquid?

Answer 1

The volume of a liquid can be measured by any instrument with specific label of liters/millileter (most standard).

Some items that can do this (in chemistry) are the beaker, the erlenmeyer flask, and for the most accuracy- the graduated cylinder.

The mass of a liquid (labelled in grams) can be found by measuring the mass of the liquid's container, the mass of the container with the liquid inside of it, and then subtracting the difference using a triple beam balance:

Mass of container and liquid combined - mass of container = mass of liquid

The density of a liquid can be found by dividing the liquid's mass by it's volume (labeled in grams per square milliliter).
A beaker
A measuring jug.

Answer 2

Liquid volume can be measured using any number of volumetric measuring devices. In a chemistry lab, for example, all of the following could be used to measure volume: pipets, burets, graduated cylinders, flasks, droppers, and more. <-- each with varying levels of accuracy of course.

Answer 3

There are various instruments that can be used. These include:

Graduated Cylinder

Erlenmeyer Flask

Beaker
