1. A Job's Method study was carried out for the reaction
   aA + bB ---> dD + fF

   Stock solutions of A and B containing 1 mmole per 10 mL of solution were prepared. These were used to prepare a series of 8 solutions containing varying amounts of A and B, but such that the total moles of A and B was maintained constant. The mass of product D obtained was measured.

   Solution	volume A solution	volume B solution	Mass product D, g
   1	0.3	3.2	0.12
   2	0.4	3.1	0.16
   3	0.5	3.0	0.2
   4	0.7	2.8	0.28
   5	0.9	2.6	0.36
   6	1.2	2.3	0.46
   7	1.75	1.75	0.35

   What is the mole ratio, b/a?
