Grahams Law and Molar Mass
The table below provides data from an effusion experiment for Gas X and Gas Y. According to Graham’s law of effusion, $$\frac{\text{rate}_X}{\text{rate}_Y} = \sqrt{\frac{M_Y}{M_X}}$$, what is the molar mass of Gas Y?
| Gas | Effusion Time (s) | Molar Mass (g/mol) |
|---|---|---|
| Gas X | 12 | 4 |
| Gas Y | 24 | ? |
A
12 g/mol
B
8 g/mol
C
16 g/mol
D
32 g/mol
