who knows the the formula of graham's law of effusion here? when time or distance is given
I'll just check if my formula is correct :)
i think it is \[\Huge \frac{r_{1}}{r_{2}}=\frac{\sqrt{d_{2}}}{\sqrt{d_{1}}}\]
@sami-21 I actually think its r(M)½ = constant? But I could be wrong
molar mass and time are given

@gjhfdfg you are correct .
I think I know how to answer it already :) anyway, thanks for your answers
in terms of molar masses \[\Large \frac{r_{1}}{r_{2}}=\frac{\sqrt{M_{2}}}{\sqrt{M_1}}\]
