We are now in a position to give the equations of the 

 curves of the molar fractions of the three chemical species and 

 of the total and partial pressures. These are

 p = 185.6 C 



The curves calculated by means of these equations are re- 

 produced in Figs. 13 and 

 14. The data found by 

 CuNAEUs are marked with 

 circlets. The agreement 

 must be considered to be 

 satisfactory, in as much as 

 we have employed as the 

 basis of calculation only the 

 vapour pressures of pure 

 acetone and ether and the 

 tangents of the partial press- 

 ure curves at the ends. Fig-. 13.
