146. Solving a chemistry problem

3. When studying the effect of surface-active additives on the crystallization structure formation of concentrated oxide suspensions
Calcium, the following experimental data were obtained (the method of a conical plastometer was used):
 
Concentration of sulfate-alcohol
bards C,%
0 0.14 0.40 0.72 1.44 7.2
Depth of immersion of the cone h · 10 3, m 2.0 1.64 0.95 0.75 0.63 0.59
 
The load value F = 9.8 H, the cone constant K = 0.4.
