CHEM 1010U Study Guide - Acetic Anhydride, Molar Mass, Chemical Formula
Document Summary
Balancing chemical equations: law of mass conservation: mass is neither created nor destroyed in chemical reactions, that means in a balanced chemical equation: The kinds of atoms on each side of the equation are the same. How many moles of each reactant will be needed. Moles of product will be produced (theoretically) Stoichiometry: chemical arithmetic: required for mole-mass conversions aa+bb => cc+dd, determining molar mass, hcl. Thursday, sept 11/14: converting from atoms to mole and mole to mass. How many moles of sucrose (c12h22o11) are in a tablespoon of sugar containing. 25. 0g cl2 x 1 mol cl2 /70. 9 g x 2mols of naoh/1 mol cl2 x 40. 0 g / 1 mol naoh. =28. 2 g naoh are needed to react with 25. 0 g cl2. 4. 50g c7h6o3 x 1 mol c7h6o3 /138. 13 g c7h6o3 x 1 mol c4h6o3/1 mol c7h6o3 x 102. 1 g. 4. 5 g c7h6o3 x 1 mol c7h6o3 /138. 13 g c7h6o3 x 1 mol.
