Calculate how many nanoparticles of magnetite in 1 gram 500nm. Figure out how many grams to be 1 part per million. I need to figure out how many ML to put into 100000 gallons of fluid to be able to capture 1 part per billion and to trillion. need calculations in excel.

Dear sir, Academics : I graduated a Master in computer science and mechanical engineering from the top French Engineering school and this can be publicly verified. Ppm is a mass ratio. Take the volumic mass Mv of magnetite, multiply it by the average volume of a particule (volume = 4/3 Pi . R^3). This is your particle mass. Multiply it per a million and divide by the voluminous mass of your liquid to know how much liquid you need to add for dilution. That’s all ! A1 : Volumic Mass Magnetite A2 : Diameter of a particle A3 : Volumic mass of water A4 : 1 000 000 (for a part in a million) A5 : Volume of water to add for 1 particle A5 = A1*(4/3*PI()*(D/2)^3)*A4/A3 I’m very very specialized in excel formulas and teaching. I have made hard exercises for people that need advanced understanding of : - Complex multi-condition Index/match formulas - Formulas in pivot tables, in number formats, in graph axis colors, in conditional formatting, and in dropdown menus. - Array-like formulas, that are equivalent to VBA loops. Like “sum of squares of values in a range”, or “min in column A for values when the text in column B is present in text column C”. - Size reduction for big data files - Time reduction for files with too many calculations I know VBA, Java, C++, Python, JavaScript. In 2008 I was already working on a program of 70 000 lines of code in C++ that calculated the braking distance of A320 airplanes.
