![]() ![]() Cover the term you wish to calculate with your forefinger.Write down the term you wish to calculate (e.g.The three equations derived from this triangle are:Ĭ = n / V n = C x V V = n/C How to use a formula triangle: ![]() The vertical line means that you must multiply.The horizontal line means that you must divide.All you need to do is remember how to draw the triangle, what letters go where, what they mean, and how to use the triangle. Manipulate the above formulas to solve Chemistry problemsįormula triangles are handy those of us who really struggle with algebra and manipulating terms.Use the formula concentration = number of moles/volume.Use the formula number of moles = mass/molar mass.The mole can be used to help you to work out other information about a substance, such as its concentration or its mass. Regardless of the element in question, one mole of atoms contains 6 x 10 23 atoms. It is a convenient way of counting atoms and allows chemists to make predictions about the masses of different substances that are involved in reactions. In Chemistry, the measure the amount of a substance in a unit is called a ‘mole’.
