How to measure mass of unknown metal using only graduated cylinder, dropper, dish, ruler funnel, and scoopula?

You can measure the mass of an unknown metal by using scale to find out its mass.
You can identify the unknown metal by finding out its density and then compare it with the density of known substances.
To find the density of the unknown metal, use weighing balance to measure the mass of the metal. And to find out its volume, use graduated cylinder to measure the differences that occur when the unknown metal is dropped inside the water in a graduated cylinder.
To calculate the density, divide the mass of the metal with its volume. The answer you obtain is the density of the metal. You can then compare your answer to densities of known substances in order to identify the unknown metal,
