The subscript outside the parentheses: (H2SO4)2
It is the number of atoms or molecules of a compound in one mole of that substance.
The number of molecules in a mol of a substance is the Avogadro number: 6,022 140 857 (74).10e23.
It is the number of fundamental particles - atoms or molecules - of a substance in 1 mole of that substance.
Avogadro's constant is the number of atoms or molecules of a substance in 1 mole of that substance.
The average amount of motion of molecules in a substance is measured by temperature. Higher temperatures indicate that the molecules are moving faster on average, while lower temperatures indicate slower average motion.
nH2O typically refers to a complex where "n" represents the number of water molecules attached to a particular compound. It is commonly used in chemistry to indicate a hydrated form of a substance.
Water
Avagadros number - The number of molecules/element that are found in one mole of the substance
One mole of any substance contains Avogadro's number of molecules, which is approximately (6.022 \times 10^{23}) molecules. This quantity is a fundamental concept in chemistry used to relate the mass of a substance to the number of molecules it contains. For example, one mole of water (H₂O) contains Avogadro's number of water molecules.
The number of water molecules it contains.
according to Avogadro number, one mole of substance = 6.022x10^23 molecules. so 2 mole =12.044 molecules of substance. the number of molecules don't depend on what the substances are but depends on the number of mole of that substance
6.0221415 × 1023this number represents the number of molecules in a "mol" of a substance
