Consider the analysis of manganese in flour by atomic absorption. A 0.1015g sample of flour digested with H2SO4 and then H2O2 and the digest solution was diluted to 50 ml.

1. 10.00ml of a blank solution (considering of the same amounts of H2SO4 and H2O2 in water as the diluted sample solution) was transferred to a 25.00ml volumetric flask and diluted to volume. This solution gave an adsorption of 0,011.

2. 10.00ml of the diluted sample solution was transferred to a 25.00ml volumetric flask and diluted to volume. This solution gave an absorption of 0.437.

3. 10.00 ml of the diluted sample solution and 5.00ml of a 41.0 pbb Mn were transferred to a 25.00 ml volumetric flask and diluted to volume. This solution gave an absorption of 0.681.

What was the concentration of manganese in the flour in ppm?
