How do the rates of diffusion of helium and sulfur dioxide compare Molar masses Helium is 4 g mol and sulfur dioxide is 64 g mol?
Helium diffusses 4 times as fast as sulfur dioxide.
How can you compare the rates of effusion of two gases in a mixture?
The rate of effusion of two gases in a mixture is inversely proportional to the square roots of their molar masses.
When you compare masses of the same volume of different substances you are doing what?
Comparing density
A determination of the masses and number of moles ofsulfur and oxygen in the compound sulfur dioxide would be studied in?
Composition stoichiometry
What is the application of grahams law?
Here is the formula: Rate1 / Rate2 = square root of (Mass2 / Mass 1) that is, the square root of the inverse ratio of their molecular masses/densities You must onsider effusion when considering Graham's law. Effusion occurs when gas molecules escape from their container through tiny holes in the container.

How long does Helium Flash in Stars Solar Masses last?
The helium flash only last for a couple of minutes.
What is hanging mass used for?
It is used to compare masses.
How do the masses of electrons compare with the masses of protons?
The mass of a proton is 1836 times greater than the mass of an electron.
What is one way to compare two masses?
Compare their weights when they're both in the same gravitational environment ... on the surface of the Earth, for example. Under those conditions, their weights will be directly proportional to their masses.
