This is the first assignment for Unit 14 BTEC Applied Science. This is one of my most worked on assignments and I can fully ensure you that covers all the key aspects of the specification in order to achieve a distinction grade. please use it as a guide on how and what to write and not copy and paste because that will count as plagiarism. A full bibliography is attached at the end. Have fun and good luck ;)

Student Exploration: Moles Vocabulary: atomic mass, Avogadro constant, conversion factor, dimensional analysis, mole, molar mass, molecular mass, scientific notation, significant figures, unified atomic mass unit Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. In the image to the right, note a dozen eggs, a dozen donuts and a dozen roses. How many of each item do you have? 2. Would a dozen of each object have the same mass? 3. Suppose you have a dozen carbon atoms, a dozen...
