When determining the manganese content in steel by the method of three standards, the blackening of the lines of the homologous pair was measured on a microphotometer: λFe = 293.690, λMn = 293.306 nm. Determine the mass fraction (%) of manganese in steel according to the data:
Option 1
Parameter standard test sample
ω (Mn),% 0.33 0.89 3.03?
SFe 1.33 1.24 1.14 1.08
SMn 0.95 1.06 1.20 0.96
