Igcse Model Questions Vol1 2020 Chemistry Question 26
Practice objective / multiple choice question 26 from the 2020 Igcse Model Questions Vol1 Chemistry examination.
A gaseous mixture of propane \(\text{C}_{3}\text{H}_{8}\) and butane \(\text{C}_{4}\text{H}_{10}\) occupies \(2.00\ \text{L}\) at STP. When the mixture is burnt completely the volume of carbon dioxide produced at STP is \(7.00\ \text{L}\). Given the molar masses \(M_{\text{C}_{3}\text{H}_{8}} = 44\ \text{g mol}^{-1}\) and \(M_{\text{C}_{4}\text{H}_{10}} = 58\ \text{g mol}^{-1}\), calculate the mass of propane present in the original mixture.
