  • Molecular Formula Determination: Calculating the Molecular Compound SN
    Here's how to determine the molecular formula:

    1. Find the empirical formula mass:

    * S (sulfur) has a molar mass of 32.06 g/mol.

    * N (nitrogen) has a molar mass of 14.01 g/mol.

    * Empirical formula mass of SN = 32.06 + 14.01 = 46.07 g/mol

    2. Determine the ratio of molecular mass to empirical formula mass:

    * Ratio = (Molar mass of molecular compound) / (Empirical formula mass)

    * Ratio = 184.32 g/mol / 46.07 g/mol = 4

    3. Multiply the subscripts in the empirical formula by the ratio:

    * Since the ratio is 4, the molecular formula is S₄N₄.

    Therefore, the molecular compound is S₄N₄ (Tetrasulfur tetranitride).
