Pharmaceutical Calculations Density: • Def.: It is a mass per unit volume of substance (1.8 g/ml). • Calculated by dividing mass by volume. Example: If 10 ml of sulfuric acid weight 18 g, Density = 18 (g) 10 (ml) = 1.8 g per ml (g/ml) Specific gravity: (.) • Def.: Weight of substance / weight of equal volume of standard substances have the same temperature. • For specific gravity of liquids and solids, water used as standard. • It is a ratio between like qua...
