Formula from Chapter 4: using chemical amount of reaction
\(n_{\mathrm{1}} = ν_{\mathrm{1}} \cdot n_{\mathrm{\ce{->}}}\)
You can use this if: you already calculated
\(n_{\mathrm{\ce{->}}}\) (e.g. in a limiting reactant problem)
\(n_{\mathrm{\ce{->}}}\) \(= 0.43\ \mathrm{mol}\)
\(ν_{\mathrm{1}}\) \(= 2\)
\(n_{\mathrm{1}}\) \(= ν_{\mathrm{1}} \cdot n_{\mathrm{\ce{->}}}\)
\(\ \ \ =2 \cdot 0.43\ \mathrm{mol}\)
\(\ \ \ =0.86\ \mathrm{mol}\)
