Na content is determined in a mineral salt. Estimated amount of NaCl in this sample is 6 1 % ( W / W ) .

Na content is determined in a mineral salt. Estimated amount of NaCl in this sample is 61%(W/W). For the analysis, 0.3568 g of the sample is weighed, transferred to a 100 mL flask and filled to the mark. After intensive mixing most of the sample dissolved (the volume of the suspended matter is insignificant).20 mL of the sample was filtered through a 0.22m pore filter. What is the volume of the filtrate, that is needed to be pipetted to a 50 mL volumetric flask, so that the estimated analyte concentration in the obtained diluted sample solution is 45g/mL?
