The unsteady-state mass balance equation for salt with first-order reaction is Eq. (6.7): In this problem Fi = Fo = F, CAi =0, and V is constant. Because the tank is well mixed, CAo = CA. Webchosen such as mass, or concentrations which can be by weight or can be molar if reactions are important. Total mass and composition Material balances can be based on total mass, mass of dry solids, or mass of particular com-ponents, for example protein. EXAMPLE 2.1. Constituent balance of milk
