Answer:
Explanation:
Graham’s Law applies to the effusion of gases:
The rate of effusion (r) of a gas is inversely proportional to the square root of its molar mass (M).
If you have two gases, the ratio of their rates of effusion is
The time for diffusion is inversely proportional to the rate.
Let CO₂ be Gas 1 and O₂ be Gas 2
Data:
M₁ = 44.01
M₂ = 32.00
Calculation
4.00 moles of sodium has a mass of 91.96 grams.
To find an element's molar mass, you can use its atomic weight.
