Final answer:Using Graham's law of effusion, C2H6 (ethane) will effuse the fastest from a mixture of HBr, NO2, and C2H6 due to its lowest molar mass.Explanation:When a gas mixture containing HBr, NO2, and C2H6 is contained and a small hole is made in the container, the gas that will effuse fastest can be determined using Graham's law of effusion. This law states that the rate of effusion for a gas is inversely proportional to the square root of its molar mass. Therefore, the lighter a gas molecule, the faster it will effuse. Considering the molar masses of HBr (approximately 81 g/mol), NO2 (approximately 46 g/mol), and C2H6 (approximately 30 g/mol), C2H6 (ethane) has the lowest molar mass and will effuse the fastest at STP (Standard Temperature and Pressure)....
