A chemistry problem by Istiaq Ansari
Diffusion of HCl and NH3 is happening from the center of two orb shapes which are connected two a cone. The cone shape can be imagined as two different cones with same r(radius) values. In one place NH3 and HCl meets and creates NH4Cl. Find the distance of the meeting point from point A.
all values given are in cm unit.

From graham's diffusion law we find the ration diffusion rate of NH3 and HCl is 1.47. The total volume of the system is 1532.1 cubic cm. From these two information we find that NH3 will travel a volume of 911.76 cm^3 at the same time that HCl will take to travel a volume of 620.24 cm^3. So HCl will not pass through the A ball only cover area of 5.29 radius inside the ball. So the distance of the meeting point from point A is 6+5.29=11.29
