What is the molecular formula of the compound CH2 with molar mass = 168 g/mol?A.C11H22B.C10H20C.C8H16D.C12H24

The molecular formula of a compound can be determined by comparing the compound's empirical formula mass to its molar mass.

Step 1: Determine the empirical formula mass of CH2. The atomic mass of Carbon (C) is approximately 12 g/mol and Hydrogen (H) is approximately 1 g/mol. Therefore, the empirical formula mass of CH2 is 12g/mol + 2(1g/mol) = 14 g/mol.

Step 2: Compare the empirical formula mass to the molar mass. The molar mass of the compound is given as 168 g/mol. Divide the molar mass by the empirical formula mass to find the number of empirical formula units per molecule of the compound: 168 g/mol ÷ 14 g/mol = 12.

Step 3: Multiply the subscripts in the empirical formula by the number of empirical formula units per molecule to find the molecular formula. In this case, the empirical formula is CH2 and we found that there are 12 empirical formula units per molecule. Therefore, the molecular formula is C12H24.

So, the answer is D. C12H24.
