## moongazer Group Title who knows the the formula of graham's law of effusion here? when time or distance is given one year ago one year ago

1. moongazer Group Title

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

2. sami-21 Group Title

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

3. gjhfdfg Group Title

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

4. moongazer Group Title

molar mass and time are given

5. moongazer Group Title
6. sami-21 Group Title

@gjhfdfg you are correct .

7. moongazer Group Title

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

8. sami-21 Group Title

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