Linear regression -> calculation of purity (pls - very desperate)?
« on: August 02, 2010, 03:44:33 AM »

According to my least squares calculation - my undiluted KCl concentration had been 13.623 g/L though the mass i originally weighed was 5.336 g.

How do i calculate the percentage of purity of KCl in the original sample mass? (I have simply diluted it)

Into what volume did you dissolve the KCl you weighed or what volume did you take that gave you the 5.336 g weight?
