can you help me solve this, this is what i have so far but is there a different way of doing this. please type solution in word. calculate how much KNO3 can be removed as solid (filtered) from a 1-kilogram solution of 60 wt% KNO3 in water (40 wt%) at 65 °C, when it is cooled to 25 °C. Note that the 60 wt% value is given on a basis of total solution mass, which is different than the values presented in the graph.
