1 liter
2 liters
4 liters
8 liters
3. Avogadro's Law states that equal volumes of all gases, at the same temperature and pressure, have the same number of .
4. The conditions of 0°C (273.15 K) and 1 atmosphere (atm) of pressure are known as .
5. Explain how the coefficients in a balanced chemical equation for gaseous reactions can represent both mole ratios and volume ratios.
