IB Chemistry: The Ultimate Isotope Abundance Calculation! (Relative Atomic Mass Explained) 🧪

Master a core concept in IB Chemistry: calculating isotope abundance from relative atomic mass! In this video, we'll solve a classic problem using a system of equations. We'll show you how to find the relative abundance of Ga-71, given that Gallium (Ar=69.72) consists of two isotopes, Ga-69 and Ga-71. We'll walk you through setting up the equations, including the key relationship that the sum of abundances equals 100%, and using the weighted average formula to solve for the unknown percentage. This is a must-know skill for your exams! #ibchemistry #isotopes #RelativeAtomicMass #chemistryteachers #chemistryhelp #ibexams #scienceeducation #examprep #ibchemistry #apchemistry #highschoolchemistry #chemistryhelp #scienceeducation #chemistrytutor #ibchemistry #highschoolhelp #isotope
