Formula from Chapter 9: definition of rate of diffusion
\(\mathrm{rate}_{\mathrm{diffusion}} = \dfrac{n_{\mathrm{gas\ area}}}{Δt}\)
\(Δt\)
\(= 1.0\ \mathrm{min}\)
\(n_{\mathrm{gas}}\)
\(= 2.3\ \mathrm{mol}\)
\(\mathrm{rate}_{\mathrm{diffusion}}\)
\(= \dfrac{n_{\mathrm{gas}}}{Δt}\)
\(\ \ \ =\dfrac{2.3\ \mathrm{mol}}{1.0\ \mathrm{min}}\)
\(\ \ \ =2.3\ \frac{\mathrm{mol}}{\mathrm{min}}\)
