Question 15 for ktg-theo

Avogadro’s Hypothesis and Molar quantities.
I. Equal volumes of all gases under the same conditions of temperature and pressure contain equal number of molecules.
II. Avogadro’s number (NA) is approximately 6.022 × 10²³.
III. The standard molar volume of an ideal gas at STP is 22.4 liters.
IV. The gas constant R is equal to the product of Avogadro’s number and Boltzmann’s constant (R = NA kB).
V. The density of a gas at fixed T and P is inversely proportional to its molar mass.
