Webb15 juni 2024 · One approach is to use the method of successive approximations. First, we recalculate the ionic strength using the concentrations of all ions, including Pb 2+ and IO − 3. Next, we recalculate the activity coefficients for Pb 2+ and IO − 3 using this new ionic strength and then recalculate the molar solubility. Webb30 apr. 2024 · We use the product-of-coefficients approach and bootstrapping techniques to estimate firm-level data from the World Bank Enterprise Survey and Innovation Follow-up Survey for five countries in Sub-Saharan Africa.
