How find empirical formula
WebFinding empirical formulae from mass data Suppose you found that 0.46 g of sodium formed 0.78 g of sodium sulfide. That means that 0.46 g of sodium combines with (0.78 - 0.46) g = 0.32 g of sulfur. Relative atomic masses: Na = 23; S = 32 It is clearest if you set your answer out as a simple table: WebThere are three main types of chemical formulas: empirical, molecular and structural.
