12. When determining tin in bronze for constructing a calibration curve, the following results were obtained: the mass fraction wSn=10.2% corresponded to ΔS = 0, the mass fraction wSn=5.2% corresponded to ΔS = –0.52. Construct a calibration graph and determine the mass fraction (%) of tin in the test sample, if ΔSx = – 0.28.
