To calculate the molar mass of the unknown gas using the effusion rate, we can apply Graham's Law of Effusion, which states:
\[ \frac{R_1}{R_2} = \sqrt{\frac{M_2}{M_1}} \]
Where:
- \(R_1\) and \(R_2\) are the effusion rates (e.g., volumes of gas effused per unit time) of the unknown gas and a reference gas, respectively.
- \(M_1\) and \(M_2\) are the molar masses of the unknown gas and the reference gas, respectively.
From the given information:
- \(M_1\) (molar mass of the reference gas) can be known (for example, if we use oxygen, it's approximately \(32.00 , \text{g/mol}\)).
- The ratios \(R_1 / R_2\) will be known based on the experimental results (the times taken for each gas to effuse).
If you provide the necessary rates (or times) and the molar mass of the reference gas, I can help calculate the molar mass of the unknown gas based on that data.
Please give me the rates or times and the reference gas used!
