**Problem: ****Tables Needed:****My calculations:**% difference for absorbance (SOLID) = [(0.336 theoretical -

0.385 nm actual) x 100%]/0.336 theoretical

% difference for absorbance (SOLID) = (-0.049 x 1)/0.336 theoretical

% difference for absorbance (SOLID) = -0.146 (

INCORRECT - 2/3 submissions)

% difference for absorbance (STOCK SOLUTION) = [(0.336 theoretical unknown -

0.962 nm actual) x 100%]/0.336 theoretical

% difference for absorbance (STOCK SOLUTION) = (-0.626 x 1)/0.336 theoretical

% difference for absorbance (STOCK SOLUTION) = -1.86 (
