Assuming oxygen diffused in 5
Hydrogen =x
Rate of diffusion is inversely proportional to the square root of its density, therefore
R1/R2 =D2/D1
5/R2 = 1/4 given O=16 and H=1
R2=20
Which is 4 times faster than 5

U can use any number u will still get the same result I just chose to use 5

hydrogen is 1
oxygen is 8
then R1/R2 =√D2/D1 =√8/1=4
option E

its actually 2.8 times as fast as Oxygen
approximately 3 times. D is correct
