A student has 10.0ml of a 0.351 M phosphate solution. The student then adds excess ammonia (NH3) and magnesium (mg2+) to the solution under slightly basic conditions to produce struvite. express the concentration of the phosphate sample in ppm. Determine the maximum mass of the struvite the student can obtain from their sample. Assume the density of the phosphate solution is 1.00g/ml. (a) concentration of phosphate solution in ppm (b) maximum mass of struvite that can be obtained
