How do the moles relate to mass and the particle of a substance?
Moles represent a specific quantity of particles, such as atoms or molecules, that is equal to Avogadro's number (6.022 x 10^23). The mass of a substance can be determined by multiplying the number of moles by the molar mass of the substance, which is the mass of one mole of that substance. This relationship allows for easy conversion between the number of particles and the mass of a substance.
How do you find the number of particles in a compound when given the mass?
To find the number of particles in a compound when given the mass, first calculate the number of moles using the provided mass and the molar mass of the compound. Then, use Avogadro's number (6.022 x 10^23 particles/mol) to convert the moles to the number of particles in the compound.
What particles make up the atomic mass number of an element?
The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
Can you increase the number of particles of a substance in a chemical reaction?
No, the number of particles of a substance is determined by the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. The number of particles remains the same before and after the reaction.

What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons

What is the origin of Avogadro's number and how is it determined?
Avogadro's number is named after Italian scientist Amedeo Avogadro, who proposed in 1811 that equal volumes of gases at the same temperature and pressure contain the same number of molecules. Avogadro's number is determined experimentally by measuring the mass of a known number of atoms or molecules and then calculating the number of particles in a mole based on this mass.
What particles make up the atomic mass number of an element?
The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.
What is the idea that kinetic energy is determined by movement of their particles?
The concept that kinetic energy is determined by the movement of particles is based on the relationship between the speed and mass of the particles. The kinetic energy of a system is directly proportional to both the mass and the square of the velocity of its particles. Therefore, the faster the particles move, the higher their kinetic energy.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
How is the number of moles determined from a known mass?
Number of moles = Total mass/Molar mass
Can you increase the number of particles of a substance in a chemical reaction?
No, the number of particles of a substance is determined by the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. The number of particles remains the same before and after the reaction.
What particles are added together to determine atomic mass?
The atomic mass of an atom is determined by the sum of the number of protons and neutrons in its nucleus. Protons have a positive charge, and neutrons have no charge. The total number of protons and neutrons in an atom's nucleus is called its mass number.
Do gases have a definite mass?
Yes, gases have mass because they consist of individual particles (atoms or molecules) that have their own mass. The mass of a gas is determined by the combined mass of its individual particles.
Atomic mass is determined by the number of protons plus the number of?
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
