the final pressure of the gas? Answer Key: Step 1: Write known variables: \( P_1 = 1.00 \, atm \) \( V_1 = 10.0 \, L \) \( T_1 = 300 \, K \) \( V_2 = 5.00 \, L \) \( T_2 = 400 \, K \) Find \( P_2 \). Step 2: Apply the combined gas law: \[ \fr
roximately 1.11 atm. 3. Stoichiometry and Gas Laws Example Problem: "How many grams of oxygen are needed to fill a 10.0 L tank at 2.0 atm and 300 K?" Solution Approach: Use ideal gas law to find moles: \[ n = \frac{PV}{RT} \] Substitute: \( P=2.0 \text{ atm} \), \( V=10.0 \te
nal pressures, V₁ and V₂ are the initial and final volumes, T₁ and T₂ are the initial and final temperatures (measured in Kelvin). This equation states that the ratio of the product of pressure and volume to temperature remains constant
