Neco 2024 Chemistry Question 48
Practice objective / multiple choice question 48 from the 2024 Neco Chemistry examination.
A 10.0 g sample of a hydrocarbon mixture contains 60 % by mass of n‑pentane (C\(_5\)H\(_{12}\)) and 40 % by mass of iso‑hexane (C\(_6\)H\(_{14}\)). Calculate the volume of oxygen gas required at STP to combust the entire mixture completely. (Molar masses: C\(_5\)H\(_{12}\)=72.15 g mol⁻¹, C\(_6\)H\(_{14}\)=86.18 g mol⁻¹; at STP 1 mol gas = 22.4 L.)
