Lesson-4.1.6- Calculate stoichiometric reacting masses, volumes of gases and solutions, and concentrations of solutions expressed in g / dm3 and mol / dm3. (Calculations involving the idea of limiting reactants may be set. Questions on the gas laws and the conversion of gaseous volumes to different temperatures and pressures will not be set.)PreviousLesson-4.1.4- Define relative molecular mass, M r, as the sum of the relative atomic masses. (Relative formula mass or M r will be used for ionic compounds.).Next
