Calculations with Solutions and Gases
Calculations with solutions and gases connect the mole concept to measurable laboratory quantities. These pages build from calculating gas volumes, through using concentration in mol dm−3, to interpreting very small concentrations expressed in parts per million.
These pages cover all four parts; the extra named ions, hydrated salts and limiting reagents follow with the supplementary set.
