Question

Equal volumes of diatomic gases under the same conditions of temperature and pressure contain the same number of
a. protons
b. ions
c. molecules
d. Dalton's "ultimate particles"

Answer 1

C ) molecules

Answer 2

it is an expression of what's properly-called Avagadro's concept: "equivalent volumes of gases lower than a similar situations of temperature and rigidity contain a similar kind of molecules" I learnt molecules and in no way debris. i imagine that molecules is the more advantageous perfect be conscious. the full foundation of gasoline equations, gasoline reactions, etc etc is thoroughly dependant and per this concept. it really is doubtless between the biggest concepts in chemistry.
