You have an 82.7 ppm Mn stock solution used to determine the amount of Mn in steel via standard additions. There is 1.0032 g of steel dissolved in acid and diluted to 250 mL in a class A volumetric flask. Solutions were prepared according to the following table, diluted to 50 mL and the absorbance values were reported. Determine the percent Mn in the steel sample.

Sample	Steel solution (mL)	H3PO4 (mL)	Standard Mn solution (mL)	KIO4 (g)	Absorbance
1 (blank)	20.0	5.0	0	0	-----
2	20.0	5.0	0	0.4	0.0786
3	20.0	5.0	1.0	0.4	0.1540
4	20.0	5.0	2.0	0.4	0.2264
5	20.0	5.0	3.0	0.4	0.3004
6	20.0	5.0	4.0	0.4	0.3785
7	20.0	5.0	5.0	0.4	0.4483

Determine the percent Mn in the steel sample.
