Calculate the [FeSCN2+] using volumes of stock solutions. Presume that all the SCN– ions react.

STANDARD SAMPLE	Volume of Fe(NO₃)₃(mL)	Volume of SCN^- (mL)	Volume of H₂O (mL)	[FeSCN²⁺]	Absorbance
1	2.5	2.0	20.5		0.1918
2	2.5	1.5	21.0		0.3239
3	2.5	1.0	21.5		0.4965
4	2.5	0.5	22.0		0.6209

Stock [Fe(NO₃)₃] = 0.200 M, Stock [SCN^-] = 0.0020 M

Any help would be greatly appreciated Please and thanks :)
