  • Molecular Formula Calculation: Determining the Molecular Formula of CH2 with a Molar Mass of 168 g/mol
    Here's how to determine the molecular formula of the compound:

    1. Find the empirical formula mass:

    * The empirical formula is CH2.

    * Calculate the molar mass of CH2: 12.01 g/mol (C) + 2 * 1.01 g/mol (H) = 14.03 g/mol

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

    * Molar mass of compound / Empirical formula mass = 168 g/mol / 14.03 g/mol = 12

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

    * CH2 * 12 = C12H24

    Therefore, the molecular formula of the compound is C12H24.
