mass [kg] = volume [m^3] * density [kg / m^3]
From Newton's 2nd law of motion, weight [N] = mass [kg] * 9.8 [m/s^2] = volume [m^3] * density [kg / m^3] * 9.8 [m/s^2].
Rearranging, we get volume = weight / (density * 9.8) [m^3]
Find the weight in [N], then you will know the volume in [m^3].
Bulk density = dry weight / volume, then by knowing the dry weight and bulk density we can calculate the volume.

Bulk density is defined as the weight per unit volume of material. Bulk density is primarily used for powders or pellets. The test can provide a gross measure of particle size and dispersion which can affect material flow consistency and reflect packaging quantity. Bulk Density ASTM D 1895 B
"Tapping" is a procedure in which a powder is placed into a graduated cylinder which is then tapped to compress the sample before its volume is measured. This reduces the amount of air trapped in the material. "Theoretical" is a method of determining the density of a mineral from the volume of a single cell.
Bulk density is the dry mass of the solids (M sub t) / total volume (V sub t) Particle density is bulk density (P sub b) / 1 minus total porosity (1-theta).
Mass divided by volume. Weigh the pellets to find the mass, then add the pellets to a measuring cylinder of water (or something of higher density than your pellets) and find the volume using the rise of water in the measuring cylinder
Calculate volume of molecule, calculate mass of molecule, compare to bulk density. Lower bulk density indicates empty space.
You're almost certainly asking about bulk density. I hear it mispronounced as "bunk" density daily. Bulk density is how much mass of a substance will fit into a given volume without any packing. It tells you about the particle density and also the packing order.
The solid density of iron ore generally lies between 3.35 and 5.6 tonnes per cubic metre, depending on the particular characteristics of the ore being considered. When the ore is broken up, air spaces are formed between the particles of ore, and the "apparent" density will be lower. The loose bulk density is one measure, the compacted bulk density is another, and the fluidised bulk density is yet another. The loose bulk density is measured on a sample of loose ore, that has not been allowed to self-compact over time, and has not been mechanically compacted. It will generally measure between 50% and 60% of the value of the solid density.
First find the bulk density of coal as per the respective grade. then multiply density with volume you will get mass
Bulk density is a mainly a property of powders, granules and other separated solids, usually used in minerals like soil or gravel. It is defined as the total amount of particles over the total volume they occupy.
