purpose of this experiment was to identify what the unknown metal was by determining what the atomic mass was. To obtain the atomic mass of the unknown metal, the number of moles of H2 gas produced from the reaction was calculated. Introduction: This lab was an application of the kinetic- molecular theory of gases. According to this theory, it stated how gaseous particles are in a constant motion where they go at random speeds as well as directions.1 According to Thomas Graham, a Scottish chemist; he
PVP and the response parameters chosen for the optimization were Dissolution efficiency at 10 min and In-vitro dispersion time. Data analysis was carried out by multiple linear regression analysis. Differential Scanning Calorimetry (DSC) and Attenuated total reflection (ATR) reports shown that there is no interaction between drug and excipients. Results: Four optimized formulations F1 to F4 are selected from the numerical optimization technique. The prepared formulations were evaluated for different
