What do you want to measure - mass, weight, volume, density. There's no answer for "measure" without indicating what is to be measured.
Use a balance, assuming this object is relatively small. If you wanted to measure the mass of the earth or moon, the procedure is somewhat different.
use a ruler to measure the lenght of each side of the object
Volume of an object is a measure of the space occupied by objects.
Unfortunately, sodium nitrate is a solid salt, and you can't really measure a solid (three dimensional object) in millimeters, which is a measure of length.
You can insert a thermometer directly into a liquid, but not into a solid. You can fairly easily measure the surface temperature of a solid object, but that does not necessarily reflect the temperature inside.

Mass is the measure of the amount of matter in an object. A solid object has to be made up of something to be solid, therefore it has mass.
The method used to measure an irregular solid by placing it in water is called dispersion. If you note the level of the water before placing the object in and the level after, you can find the volume of the object by calculating the difference.
multiply it Length- Width - Height , or measure the volume of a container of water then stick the object in and measure the volume of the object+water then subtract the volume of the water then you have the volume
by measuring the amount of water it displaces
yes
measure with a ruler the length, width and height and multiply lxwxh
