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
The number of water molecules it contains.
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.
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
