Question

who knows the the formula of graham's law of effusion here? when time or distance is given

Answer 1

I'll just check if my formula is correct :)

Answer 2

i think it is
\[\Huge \frac{r_{1}}{r_{2}}=\frac{\sqrt{d_{2}}}{\sqrt{d_{1}}}\]

Answer 3

@sami-21 I actually think its r(M)½ = constant? But I could be wrong

Answer 6

@gjhfdfg you are correct .

Answer 7

I think I know how to answer it already :)
anyway, thanks for your answers

Answer 8

in terms of molar masses
\[\Large \frac{r_{1}}{r_{2}}=\frac{\sqrt{M_{2}}}{\sqrt{M_1}}\]
