Find the fum of the quantities of real acid in loo parts of the 

 mixture, then find the refulting fp. grav. by the 2d problem, if the 

 given fp. gravities be extratabular, the operation muft be more te- 

 dious, as the acid contents of each muft be found. 



Problem jth. 



The quantity of an acid liquor requifite to faturate 100 parts 

 of any bafis being found, to find the fp. grav. of that acid liquor. 



ift. Find by the 4th table the quantity of real acid requifite 

 to faturate 1 00 parts of the given bafis, it is then plain that the 

 given quantity of acid liquor contains the requifite quantity of 

 real acid, fince it is fuppofed to faturate 100 parts of the bafis 

 and hence we may fee how much 100 parts of fuch acid liquor 

 contains of real acid, and if this laft found quantity be in the 

 table, its fp. grav. will be feen, but if extratabular, its fp. grav. 

 muft be fought by the ad probJem. 



Problem 6th. 



The quantity of real acid requifite to faturate roo parts of any
