Chemistry · Secondary 3 · Hard · Diffusion
A student diffuses two gases through the same small hole at room temperature. Gas X has relative molecular mass 8 and takes 30 s to diffuse. Gas Y has relative molecular mass 32. Assuming the speed of diffusion is inversely proportional to the square root of relative molecular mass, how long will Gas Y take to diffuse?
- 15 s
- 30 s
- 45 s
- 60 s
