Solution:

At Normal Temperature and Pressure (NTP), 1 mole of any ideal gas occupies 22.4 liters and contains Avogadro's number (\(6.022 \times 10^{23}\)) of molecules.

Since each gas sample has the same volume (1 cm³) and is at NTP, they all contain the same number of molecules. This is because, at the same conditions of temperature and pressure, equal volumes of gases have equal numbers of molecules (Avogadro's Law).

Answer: All samples have the same number of molecules.
