Youve got a 5.5M of an unknown solution. You know that it is 0.212g/L. You want to know the percent by mass of Iron. You know that the iron has a concentration of 25 ppm. How do you find the percent by mass of Iron? Thank You!!

ppm in a liquid solution is mg/L, so get both into the same units to figure it out.
0.212 g/L = 212 mg/L, which is the total concentration. Iron's concentration is 25 mg/L, so the mass percent of iron will be 25/212 or 11.8%.
