Na content is determined in a mineral salt. Estimated amount of NaCl in this sample is $61\%($W$/$W$).$ For the analysis, $0\mathrm{.}3568$ 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 $0\mathrm{.}22$m 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 $45$g$/$mL$?$
