Pythagoras c. 2. = a. 2. + b. 2 . where c is the hypotenuse = the longest side. Pythagoras. . c. 2. = a. 2. + b. 2 . . so c = (a. 2. + b. 2 . )^0.5. a. 2. = c. 2. - b. 2 . You should know this for the quiz!. Empirical and Molecular Formulae. Empirical Formula. If needed, change % to g.. Do . a molar conversion to change from . g. mol. Divide each of these numbers by the smallest number. Objectives. To learn how to write formulae for compounds. Outcome: you should be able to write the formulae for inorganic covalent compounds and ionic compounds comprising single atom ions or polyatomic ions.. equations and formulae. Equations and formulae are used in Physics, Chemistry and Biology. Sometimes you will need to rearrange them to work something out.. To rearrange them, you need to understand what they mean.. Objectives. To learn how to work out the percentage composition by weight of a compound. To use percentage composition to work out empirical formulae. Percentage compositions. This means what percentage of each element is present in a compound, and therefore tells you what masses of each element are present in any given mass of a compound. .
