Graham’s Law Demonstration of Graham’s Law The diffusion of one substance through another is relatively slow process.. Bromine vapor is diffusing graduated cylinder. After several hours, bromine vapors are near the top of the cylinder. Mathematical Equation Definition of Graham’s Law Graham's law states that the rate of effusion of a gas is inversely proportional to the square root of its molecular weight. Graham's Law can also be used to find the approximate molecular weight of a gas if one gas is a known species, and if there is a specific ratio between the rates of two gases. Graph of graham Law

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
