Graham’s Law Calculator Online

Output: m/s

In the fascinating world of physics and chemistry, the concept of gas diffusion and effusion often boggles many minds. However, these complex processes are beautifully explained through Graham’s Law. To simplify calculations based on this principle, we introduce Graham’s Law Calculator, a unique tool that has turned an intricate concept into an effortless computation.

Definition

Graham’s Law, named after Scottish chemist Thomas Graham, is a principle that describes the relationship between the molar masses of gases and their rates of diffusion or effusion. The law states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. Graham’s Law Calculator is a digital tool that performs these calculations effortlessly, falling under the category of Physics and Chemistry calculators.

Detailed Explanations of the Calculator’s Working

Graham’s Law Calculator operates by taking four inputs: the rates of effusion or diffusion and the molar masses of two different gases. After inputting these values, the calculator uses the formula derived from Graham’s Law to compute the ratio of the rates of effusion or diffusion of these gases. The calculator then presents the result, giving users a quick and accurate understanding of these complex processes.

The Graham’s Law Formula and Variable Descriptions

The formula used by Graham’s Law Calculator is Rate1/Rate2 = √(Molar mass2/Molar mass1). Here, Rate1 and Rate2 represent the rates of effusion or diffusion of the first and second gas respectively, while Molar mass1 and Molar mass2 represent their respective molar masses. This formula effectively shows the inverse relationship between a gas’s rate of effusion or diffusion and its molar mass.

Example

Consider two gases, helium (He) and argon (Ar), with molar masses of 4 g/mol and 40 g/mol respectively. If the rate of diffusion of helium is 5 m/s, Graham’s Law Calculator will calculate the rate of diffusion of argon based on the provided data, making this complex calculation simple and error-free.

Applications

Chemical Industry

In the chemical industry, Graham’s Law is applied to separate a mixture of gases, and the calculator simplifies this process.

Environmental Studies

It aids in understanding the dispersion of pollutants in the air, contributing to effective environmental studies and solutions.
