⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. The relationship between the volume of a gas, moles, and the molar volume. Using the equation: Volume of Gas (dm³) = Moles x 24. This calculation applies to any gas at room temperature and pressure (RTP). 2. Calculating the volume of a gas from a known number of moles. 3. Rearranging the equation to calculate the number of moles from a known gas volume. 4. Two-step calculations to find gas volume when given mass. First, calculating moles using the mass and relative formula mass (Mr). Second, using the moles to calculate the volume. 5. Calculating the volume of a gaseous product from the volume of a gaseous reactant. Using molar ratios from a balanced chemical equation. A shortcut for converting directly between gas volumes using the molar ratio. 6. The conditions under which the molar volume of a gas is 24 dm³. ** EXAM BOARD SPECIFIC INFO ** AQA - Separate science and higher tier only IGCSE Edexcel - Separate science and higher tier only Edexcel - Separate science and higher tier only OCR 21st Century - Separate science and higher tier only OCR Gateway - Separate science and higher tier only ** CHAPTERS ** 0:00 Introduction 0:43 Calculating Volume from Moles 0:57 Calculating Moles from Volume 1:24 Two-step Calculations Involving Mass 2:38 Calculating Reacting Gas Volumes 5:57 Importance of Room Temperature and Pressure (RTP) ** PLAYLISTS ** • KS3 Biology • KS3 Chemistry • GCSE Maths (9-1) • GCSE Biology (9-1) • GCSE Chemistry (9-1) • GCSE Physics (9-1) • A-Level Biology #GCSE #Chemistry #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
