Solve this problem using the appropriate law.

uranium contains two isotopes, u-235 with an atomic mas of 235 g/mol, and u-238 with an atomic mass of 238g/mol. u-235 is needed as a fuel in nuclear reactors. until recently, the method used to separate u-235 from u-238 was by gas diffusion. use u-235 as r1 and u-238 as r2 and determine the rate of diffusion and which gas will diffuse faster.

u-235 diffused 1.01 times slower than u-238
u-235 effused 1.01 times faster than u-238
u-235 effused 2.01 times slower than u-238
u-235 diffused 1.01 times faster than u-238
u-235 diffused 10.01 times faster than u-238
