Answer to Question #115332 in General Chemistry for Fcfff

Question

Use Graham’s law to calculate the velocity of, F2 if the velocity of chlorine is 256 m/s at a certain temperature.

Answer 1

Graham’s law for the two gases is 

r1/r2=*square root of*M2/M1

where r1 and r2 are the velocity of the first and second gas, respectively

And where M1 and M2 are the molar mass of the first and second gas, respectively

r(F2)=349m/s
