In the given problem, mass of the solute, mass of the solvent and volume of the solution is known. However, only information related to the masses are sufficient to compute the mass percentage of the components.Answer and Explanation:
Chemistry is such a broad subject and one so full of detail that it is easy for a newcomer to find it somewhat overwhelming, if not intimidating. The best way around this is to look at Chemistry from a variety of viewpoints: How Chemistry relates to other sciences and to the world in ...
Zinc chloride can attack metal oxides (MO) to form MZnOCl2, which is the principle behind its use as a metal flux in welding. ZnCl2 dissolves the dense oxide layer on the metal surface, exposing the metal. This flux is obtained by dissolving zinc foil in dilute hydrochloric acid until no...
