1. What is the molar volume of any ideal gas at Standard Temperature and Pressure (STP)?
1.0 L
2.24 L
22.4 L
224 L
2. Which of the following is NOT a component of the Ideal Gas Law equation?
Pressure (P)
Volume (V)
Mass (m)
Temperature (T)
1. The Ideal Gas Law is expressed by the equation PV = nRT, where 'R' is the gas constant.
2. When performing stoichiometric calculations involving gases not at STP, the Gas Law must be used.
3. One mole of any gas at 0°C and 1 atm occupies a volume of L.
1. Calculate the volume occupied by 5.0 moles of nitrogen gas (N₂) at STP.
2. A reaction produces 10.0 L of hydrogen gas (H₂) at 27°C and 750 mmHg. How many moles of H₂ were produced? (R = 0.0821 L·atm/(mol·K))
1. All gases behave ideally at all temperatures and pressures.
True
False
2. According to Avogadro's Law, equal volumes of all gases at the same temperature and pressure contain equal numbers of molecules.
True
False
Consider the reaction: 2 KClO₃(s) → 2 KCl(s) + 3 O₂(g)
If 100.0 g of KClO₃ decomposes completely, what volume of oxygen gas (O₂) would be produced at 25°C and 1.2 atm?
