Formula from Chapter 4: chemical amounts in a chemical reaction (stoichiometry)

\(\dfrac{n_{\mathrm{1}}}{ν_{\mathrm{1}}} = \dfrac{n_{\mathrm{2}}}{ν_{\mathrm{2}}}\)     

You can use this if: you have a balanced chemical equation describing the reaction at hand
You can use this if: \(n_{\mathrm{1}}\) and \(n_{\mathrm{2}}\) refer to chemical amounts that reacted

\(n_{\mathrm{1}}\) \(= 1.43\ \mathrm{mol}\)


\(ν_{\mathrm{1}}\) \(= 2\)


\(ν_{\mathrm{2}}\) \(= 3\)


\(n_{\mathrm{2}}\) \(= \dfrac{n_{\mathrm{1}}}{ν_{\mathrm{1}}} \cdot ν_{\mathrm{2}}\)

\(\ \ \ =\dfrac{1.43\ \mathrm{mol}}{2} \cdot 3\)

\(\ \ \ =0.7150\ \mathrm{mol} \cdot 3\)

\(\ \ \ =2.15\ \mathrm{mol}\)
