Sodium fluorosilicate consumption

Given the flow to be treated, the desired dosing rate and, the dilution of the solution to be prepared, calculates the daily consumption of the sodium fluorosilicate, the number of 50 kg bags consumed per day and the dosing flow. Suppose that the purity of the product is 90% and the fluoride content in the product is 49%.
