on a balance
Something to determine volume (like a bucket of water or a ruler), and a balance to determine mass. Divide the mass of the block by its volume to find the density of the block.
You need a scale to measure the weight and ways to submerge the block and measure the water to determine the volume.
To measure the density of a regularly shaped solid, common tools used include a balance or scale to measure the mass, and a ruler or caliper to measure the dimensions (length, width, and height) of the solid. With this information, the density can be calculated by dividing the mass by the volume of the solid, which can be determined by multiplying the three dimensions together.
A set of scales to weigh it and a container of water big enough to submerse it with some means of measuring the water displaced. Density = weight or mass divided by volume

There are many online tools are available for checking keyword density. I have mention some tools which are given below:- seobook.com/general/keyword-density/ smallseotools.com googletheplanet.com seoquake.com/ You can check keyword density by using these tools. I had checked my site (Royzez) keyword from seoquake and smallseotools.

Well density is weight divided by volume so a scale and a ruler
