Final answer:
To calculate the total pressure in the flask, you need to calculate the partial pressure of each gas and then add them together. You can use the formula Partial pressure = (moles of gas / total moles of gas) * total pressure to calculate the partial pressures of N₂, CO, and H₂. The total pressure in the flask can be found using the ideal gas law PV = nRT.
Step-by-step explanation:
To calculate the total pressure in the flask, we need to calculate the partial pressure of each gas and then add them together. The partial pressure of each gas can be using the formula: Partial pressure = (moles of gas / total moles of gas) * total pressure For N₂: Partial pressure = (0.0388 mol / total moles of gas) * total pressure For CO: Partial pressure = (0.147 mol / total moles of gas) * total pressure For H₂: Partial pressure = (0.0803 mol / total moles of gas) * total pressure.
To find the total pressure in the flask, we need to use the ideal gas law: PV = nRT Substituting the given values: (total pressure) * (5.73 L) = (0.0388 mol + 0.147 mol + 0.0803 mol) * (0.08206 L-atm/mol-K) * (25 °C + 273) Solving for the total pressure, we get: total pressure = [(0.0388 mol + 0.147 mol + 0.0803 mol) * (0.08206 L-atm/mol-K) * (25 °C + 273)] / (5.73 L)
