According to Avogadro's law equal volumes of all gases under same pressure have equal numbers of molecules.-

Gram molar volume of all gases can be determined by ________.

Mass number is equal to the _______.

Three vessels of equal capacity have gases at the same temperature and pressure. The first-vessel contains neon (monoatomic), the second contains chlorine (diatomic), and the third contains uranium hexafluoride (polyatomic). Do the vessels contain an equal number of respective molecules? Is the root mean square speed of molecules the same in the three cases? If not, in which case is υrms the largest?
