Graham's Law predicts that the ratio of the rate of effusion of gas X to the rate of gas Y equals the square root of the INVERTED ratio of their molar masses:
Rate of X/Rate of Y = SQRT(My/Mx)
What is the ratio of rate of effusion of Helium to Nitrogen gas? Enter your answer to two decimal places.
I got 1.87 as my answer, but apparently that's not right.
