Neco 2022 Physics Question 33
Practice objective / multiple choice question 33 from the 2022 Neco Physics examination.
A 2.0\,L container initially contains \(0.05\ \text{mol}\) of an ideal gas A at \(300\ \text{K}\) and a vacuum. The gas is heated to \(450\ \text{K}\). Afterwards a valve is opened to a reservoir of gas B that is at \(1.0\ \text{atm}\) and \(300\ \text{K}\). Gas B enters the container until the total pressure inside reaches \(2.0\ \text{atm}\) (still at \(450\ \text{K}\)). Assuming ideal behaviour, calculate the number of moles of gas B that entered the container (to three significant figures).
