Protons and neutrons have almost the same mass.
Electrons are the only particles in all atoms to have the same mass, about 0.501 MeV.

You will have to do an experiment to determine the answer. You will need to think about having equal concentrations of salt or sugar in the cubes. The size of the molecules/particles is different. So 100 g of salt does not have the same number of molecules/particles as 100 g of sugar. The ratio of particles is 1:4.6 for the same mass of sugar to salt. You can see that this is not an easy question to answer. Which melts faster if the mass of salt and sugar is the same? Which melts faster if the number of particles is the same? The next problem is that salt actually separates into two particles when dissolved in water, sodium ions and chloride ions whereas sugar does not. So one salt particle is actually two ions and the ratio of particles now becomes salt:sugar = 2.3:1 for the same mass of substances. This sounds like a great project for someone to investigate.
One of the particle theory's points is that there are unseen spaces between particles, another is that particles are always moving. Therefore, combining those two points, the more the particles move, the bigger the spaces between them which is to say that, take oxygen and mercury for example, oxygen is a gas at room temperature, therefore, the particles are moving faster than that of mercury, which is liquid at room temperature, meaning that, they have different densities
Subatomic particles are measured in amu's--atomic mass units. Protons and neutrons are both approximately 1 amu, and electrons have a mass so much less as to be negligible (about 1/2000 that of a proton).
Just because two ojects occupy the same volume does not mean that they have the same mass. For example: If I have two boxes of the same dimension (volume) and fill one with hammers and the second with feathers. are they the same mass? Of course not. another way of looking at the problem at hand would be to take a tone of hammers and a tone of feathers. which one occupies the most space? the feathers of course. so to have the same mass as the hammers, the feathers need to occupy more volume.
Different objects contain different amounts of matter, even if they are the same size. Therefore, two objects of the same size can have different masses.
These particles are: proton and neutron.
Proton and neutron.
The protons and the neutrons make up the atomic weight of an atom of an element, they have roughly the same mass and electrons have so little mass that they're negligible.
Composite subatomic particles (such as protons or atomic nuclei) are bound states of two or more elementary particles. For example, a proton is made of two up quarks and one down quark, while the atomic nucleus of helium-4 is composed of two protons and two neutrons.
Protons and neutrons have about the same mass, with the neutron being slightly more massive.
No two subatomic particles have the exact same mass. The proton and the neutron, however, come close. Neutrons are heavier than protons by only 2.3 X 10-30 kg.
These particles are: proton and neutron.
No. The two phrases have almost nothing to do with each other at all.
They are the same. Momentum is the product MV - mass times velocity. KE = 0.5 MV2
alpha particles consist of two protons and two neutrons (helium nucleus) logically one neutron can not have a larger mass than two neutrons and two other subatomic particles of a similar mass
An alpha particle is two protons and two neutrons (same as a Helium nucleus) so when a nucleus ejects an alpha it will defintely have less mass. Also it will be a new element because it has two less protons.
It is possible.
