At a particular pressure and temperature, nitrogen gas effuses at the rate of 79 mL/s. Under the same conditions, at what rate will sulfur dioxide effuse?

Rate of Sulfur dioxide : 2730.44 mL/s

Graham's law: the rate of effusion of a gas is inversely proportional to the square root of its molar masses or  

the effusion rates of two gases = the square root of the inverse of their molar masses:  

or  

MW of N₂ = 28 g/mol

MW SO₂ = 64 g/mol
