Neco Model Questions Vol1 2025 Physics Question 26
Practice objective / multiple choice question 26 from the 2025 Neco Model Questions Vol1 Physics examination.
A rigid container of volume \(2.00\ \text{L}\) contains an ideal gas at a temperature of \(300\ \text{K}\) and a pressure of \(1.00\ \text{atm}\). The gas is heated to \(450\ \text{K}\), causing the pressure to rise. While the temperature is held at \(450\ \text{K}\), a valve is opened and gas escapes until the pressure returns to \(1.00\ \text{atm}\). If the gas is nitrogen (molar mass \(28.0\ \text{g\,mol}^{-1}\)), calculate the mass of gas that escaped. Give your answer to two decimal places in grams.
