*The number of molecules in a given quantity of a substance depends on the _____ of that substance
Answers
Explanation:
The answer is mass or molar mass
Answer:
In chemistry, the amount of substance in a given sample of matter is defined as the number of discrete atomic-scale particles in it divided by the Avogadro constant NA. In a truly atomistic view, the amount of substance is simply the number of particles that constitute the substance.[1][2][3] The particles or entities may be molecules, atoms, ions, electrons, or other, depending on the context. The value of the Avogadro constant NA has been defined as 6.02214076×1023 mol−1. In the truly atomistic view, 1 mol = 6.02214076×1023 particles (the Avogadro number) [4] and therefore the conversion constant is simply NA = 1.[3] The amount of substance is sometimes referred to as the chemical amount.
The mole (symbol: mol) is a unit of amount of substance in the International System of Units, defined (since 2019) by fixing the Avogadro constant at the given value.

. There are proposals to replace "amount of substance" with more easily-distinguishable terms, such as enplethy[6] and stoichiometric amount.[5]
The IUPAC recommends that "amount of substance" should be used instead of "number of moles", just as the quantity mass should not be called "number of kilograms".
