Hint: Gram molecules can be defined the same as that of a mole. Gram molecules are the total number of molecules in one mole of substance.Gram molecule is defined as the number of grams of a substance that is the same as the relative molecular mass of that substance.
Complete step by step answer:
First of all, let's understand about the chemical compound sulfuryl chloride. It is an inorganic compound with the chemical formula . It is a colorless liquid with a pungent smell at the room temperature. Sulfur chloride is the source of chlorine gas. The IUPAC name of is sulfuryl dichloride.
In the question, we have to find the gram molecules of of . Gram molecules are the same as molecules. Gram molecules are defined as the number of moles present in the given mass of the substance.
i.e., …. (i)
The molecular mass of a substance is the average relative mass of its molecules as compared with an atom of carbon isotope or for a compound, it is defined as the combined atomic mass of all elements present in the compound. So, the molecular mass of can be calculated as
We know that atomic masses of sulphur, oxygen and chlorine are respectively. Thus, the molecular mass of becomes =
Gram molecules =
Hence, the answer is option (A).
Note:
The molecular mass of a substance expressed in grams is called the gram molecular mass. This amount is also called one gram molecule.The molecular mass (m) is the mass of a given molecule: it is measured in daltons (Da or u). Different molecules of the same compound may have different molecular masses because they contain different isotopes of an element.
