The molar mass of a compound is the sum of the molar masses of its individual atoms. With a molar mass of approximately 42 g, a molecular formula of C2H4 (ethene) fits the criteria, where two carbon atoms (212 g/mol) and four hydrogen atoms (41 g/mol) yield a total molar mass close to 42 g/mol.
The molecular formula of compound CH2 with a molar mass of 42.0 g/mol is C2H4, which is ethylene. Each carbon has a molar mass of 12.0 g/mol, and each hydrogen has a molar mass of 1.0 g/mol, totaling 42.0 g/mol.
The molecular formula of the compound CH2 with a molar mass of 168 is C7H14. This molecular formula satisfies the condition of having two hydrogen atoms bonded to each carbon atom, resulting in a molar mass of 168 g/mol.
The molecular formula of the compound is C2H4, which has a molar mass of 28 g/mol. Since the given compound has a molar mass of 42.0 g/mol, it must include an additional CH2 group, resulting in the molecular formula C2H6.
The molar mass of CH2 is 14 g/mol (carbon: 12 g/mol, hydrogen: 1 g/mol). To get a molar mass of 168 g/mol, we need to multiply CH2 by 12. The molecular formula for the compound with a molar mass of 168 g/mol would be C12H24.
The molecular formula of the compound CH2 with a molar mass of 168 g/mol is C8H16 since the molar mass of carbon is approximately 12 g/mol and the molar mass of hydrogen is approximately 1 g/mol. This is calculated by multiplying the subscripts in CH2 by their respective atomic masses and then calculating the total molar mass.

The molecular formula of a compound can not be determined solely based on its molar mass. In this case, without additional information, it is not possible to determine the molecular formula of the compound CH2.
The molecular formula of compound CH2 with a molar mass of 42.0 g/mol is C2H4, which is ethylene. Each carbon has a molar mass of 12.0 g/mol, and each hydrogen has a molar mass of 1.0 g/mol, totaling 42.0 g/mol.

The molar mass of CH2 is 14 g/mol (carbon: 12 g/mol, hydrogen: 1 g/mol). To get a molar mass of 168 g/mol, we need to multiply CH2 by 12. The molecular formula for the compound with a molar mass of 168 g/mol would be C12H24.
The molecular formula of the compound CH2 with a molar mass of 168 g/mol is C8H16 since the molar mass of carbon is approximately 12 g/mol and the molar mass of hydrogen is approximately 1 g/mol. This is calculated by multiplying the subscripts in CH2 by their respective atomic masses and then calculating the total molar mass.

The molecular formula for a compound with a molar mass of 84 g/mol and a CH2 composition would be C4H8. This can be calculated by dividing the molar mass by the molar mass of a CH2 molecule (14 g/mol), which gives 6.
C = 12H = 1 x 2 = 2-----------------total = 14 g/mole for empirical56.11/14 = 4.00 so there are 4 empirical formulae in 56.11 gChemical formula = C4H8
The unit CH2 has a gram atomic mass of 12.011 + 2(1.00794) or about 14. 42.0/14 = 3; therefore the molecular formula is C3H3.
