Either a 100 mL or a 50 mL
The 50 mL is better because you can see the meniscus against the graduated lines of the cylinder better.
beaker
A graduated cylinder is used to measure the volume, or capacity of water. Or to just measure Water.
Fill the graduated cylinder with water, and measure the volume. Now put the item in, measure the water's volume again, and take the difference
graduated cylinder
You can put water in the graduated cylinder and drop the solid in and see how much the water rises
not quite. you can measure volume in a graduated cylinder. you can use a scale, water, and a graduated cylinder to find out the density of an object by filling the graduated cylinder to an easily calculated point (250) then dropping your object in the water making sure none splashes out then measure the difference, then weigh it and divide the mass by volume to get density.
A meniscus is the curvature of the surface of the water. Water "sticks" to the walls of the graduated cylinder, but only on the sides and not the middle, so you measure water from the meniscus
Graduated Cylinder (A+)
You use a graduated cylinder to measure the volume of the rock with the water and the water without the rock
it is probably called figure it out, it is curved because glass is sticky. When you measure the volume from a graduated cylinder, measure at the bottom of it. It is called the meniscus.
Depending on how accurate you want to be you can use a variety of methods. Common methods include the following (with increasing level of accuracy) 1) graduated cylinder 2) volumetric pipette. 3) Calibrated micro-pipette (may require more than one transfer)
You can use a gas syringe. Alternatively you can trap the gas over water in a graduated vessel.
