Mass percentage of al2o3
WebIf the sample was pure NaCl, the % of chlorine by mass would be 61%. If it were pure LiCl, it would be 84%. We can use these two points to draw a line: percentage chlorine by mass = 61% + 23% * percentage LiCl by mass. This becomes 73% = 61% + 23% * x. Solving for x gives x = 52%. So 52% of the sample by mass is LiCl and 48% is NaCl.
