Obviously equimolecular surfaces are given by (Mv) 3, where M is the molecular weight of the substance, for equimolecular volumes are Mv, and corresponding surfaces the two-thirds power of this.
Hence S may be replaced by (Mv) 3.
Since the volume is constant, we have the condition mv'--l-(I-m)v"=constant.
If 2mu 2 denote the mean value of 2mu 2 averaged over the s molecules of the first kind, equations (3) may be written in the form Z mu g = 2 mv 2 = 2 mw 2 = 2x,0 2 1 =.
The majority of members in the MV accreditation scheme are pedigree breeders who sell quality, healthy breeding stock at premium prices.
