If you want to know the percent composition of the … WebPercent concentration by mass is defined as the mass of solute divided by the total mass of the solution and multiplied by 100%. So, c% = msolute msolution ⋅ 100%, where. msolution = msolvent + msolute. There are two ways to change a solution's concentration by mass. Adding more solute - making the solution more concentrated;
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.
