CCl, with a molar mass of 189.83 g/mol, is likely referring to carbon tetrachloride (CCl₄) or a related compound where carbon is bonded to chlorine atoms. The molar mass indicates the weight of one mole of the substance, which consists of one carbon atom and four chlorine atoms. Carbon tetrachloride is a colorless, volatile liquid historically used as a solvent and in fire extinguishers, although its use has declined due to environmental concerns.

The mass of 35 gmoles of carbon monoxide ( CO ) is given by : m = ( n ) ( M ) m = ( 35 gmol ) ( 28.00 g / gmol ) = 980 g <----------------
The notation "gmol⁻¹" refers to grams per mole, which is a unit of measurement used in chemistry to express the molar mass of a substance. It indicates how many grams of a substance are contained in one mole of that substance. For example, if a compound has a molar mass of 18 gmol⁻¹, it means that one mole of that compound weighs 18 grams. This unit is essential for converting between the mass of a substance and the amount of substance in moles.
The rate of diffusion is inversely proportional to the square root of the molar mass of the gas. Since sulfur dioxide has a molar mass twice that of oxygen, it will diffuse at a slower rate compared to oxygen.

gmol-1 refers to grams per mole and is a unit of measurement commonly used in chemistry to express molar mass or molecular weight. It represents the mass of one mole of a substance in grams.

Carbon monoxide, CO, has one atom of carbon and one atom of oxygen. The molar mass of carbon is 12.0107 g mol-1 and the molar mass of oxygen is 15.9994 g mol-1, so the molar mass of CO is 28.0101 g mol-1.
The rate of effusion of a gas is inversely proportional to the square root of its molar mass. Helium has a molar mass of 4.0 g/mol, while sulfur dioxide has a molar mass of 64 g/mol. Therefore, the rate of effusion of SO2 will be √(4.0/64) = 1/4 times that of helium. In other words, sulfur dioxide will effuse more slowly than helium.
The molar mass of the substance is 228.1 g/mol. This is calculated by dividing the mass (62.5 g) by the number of moles (0.274 mol).
