Atoommassa

What is relative atomic mass (Ar)?

Indicates how much heavier an atom is compared to a reference mass.

How is relative molecular mass (Mr) calculated?

Sum of the atomic masses of all atoms in a molecule.

What defines a mole (n)?

Represents 6.022 x 10^23 particles of a substance.

What is molar mass (Ma)?

Mass of one mole of particles, expressed in g/mol.

What is mass concentration (C)?

Amount of solute mass per unit volume of solution.

How does molar concentration (C) differ from mass concentration?

Expresses amount of solute in moles per unit volume.

What happens if you increase the amount of solute in a solution?

Concentration of the solution increases.

What is the formula to calculate mass (m) from moles (n) and molar mass (Ma)?

m = n × Ma.

How do you determine the number of particles (N) in a substance?

N = n × NA, where NA is Avogadro's number.

What is the relationship between volume (V) and molar concentration (C)?

C = n / V, where n is the number of moles.
