Question

How is the unit for dissolved oxygen is mg/L using this formula? Show the factor-label method.
Given:
V1= 10 mL
V2= 50 mL
V3= 4 mL
V4= 50 mL
N= 0.0250 N

(Vi × N × E x 1000) [V¼(V2 – V3)/V2] c(O2) (mg/L) = - Here, V1 Volume of titrant Na2 S2O3 (ml) V2 = Total volume of water sample (ml) V3 = Volume of (MNSO4 + KI solution) added (ml) V4 Volume of analyte taken in titration E Equivalent weight of O2 N = Normality of Na2 S2O3 solution
