This is usually done by weighing. On Earth, mass and weight are proportional; in fact, balances are usually calibrated for mass units, even if some of them really determine the weight.
He discovered that you have to find the volume, mass, and density of something
The mass of an object can be expressed in mass per unit or in total mass. Total mass represent the full amount.
% of volume = 100*(volume of substance that you are interested in)/(total volume) % of mass = 100*(mass of substance that you are interested in)/(total mass).
Use a digital mass scale or a triple-beam-balance scale to find the mass of a regular solid.
it is the ratio of mass of saturated vapour to the total mass of liquid
find the mass of the container you will be using to measure something. The fill the container with ur substance. Measure it. Then subtract the mass of the container from the total mass
The mass of the solution will be equal to the mass of the solute plus the mass of the solvent. However, the total mass does not change.
mass fraction of Substance A = (mass of Sub. A) / (total mass)
the total mass of the particles that something is made of
Subtract the mass of the beaker from the total weight.
You can't
mass/volume
Mass of the contained material = Total mass (mass of the container + mass of the material) - Mass of container
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
For the molar mass make the sum of the atomic weights of the elements contained in the molecule.

Yoy need to know the molar mass of this solute and the mass of the solute:moles = total mass/molar mass
