Gas Laws

Step 1: Calculate the moles for each substance.
For nitrogen (N), the molar mass is 14 g/mol, so 14g corresponds to 1 mole.

For magnesium (Mg), the molar mass is 24 g/mol, so 24g corresponds to 1 mole.

Step 2: Identify the mole ratio.
Since both nitrogen and magnesium have equal molar quantities (1 mole), the ratio of moles is 1:1.

Step 1: Review the gas laws.
Boyle’s law, Charles' law, and Gay Lussac's law all describe relationships between pressure, volume, and temperature in gases.
Hooke's law, however, relates to the behavior of springs and is not a gas law.
Step 2: Identify the incorrect option.
Hooke’s law is unrelated to gases; it describes the behavior of materials under stress and strain, making it the correct answer.

Step 1: Van der Waals equation. The van der Waals equation for real gases is an adjustment to the ideal gas law.
It accounts for intermolecular forces and the finite size of molecules.
The equation is: where is pressure, is volume, is temperature, is the gas constant, is the measure of the attraction between particles, and is the volume occupied by the gas molecules themselves.
