Analysis of a Substance Composed of Carbon and Hydrogen

The chemist conducted an analysis of a certain substance and determined that it consists only of carbon and hydrogen. The mass fraction of hydrogen in the substance is stated to be 11.7%. The question is whether this substance can have a relative molecular mass of 111.

To answer this question, we need to consider the composition of the substance and calculate its relative molecular mass.

Calculation of Relative Molecular Mass

The relative molecular mass of a substance is the sum of the atomic masses of all the atoms in its molecular formula. In this case, the substance is composed of carbon (C) and hydrogen (H).

To calculate the relative molecular mass, we need to know the number of carbon and hydrogen atoms in the molecule. However, this information is not provided in the question. Without the molecular formula or the number of atoms, it is not possible to determine the relative molecular mass of the substance.

Therefore, based on the given information, we cannot determine whether the substance can have a relative molecular mass of 111.
