A student performs a lab, diluting 0.50 mL of cola to 125.0 mL, and then measures a small portion of the diluted cola in a spectrophotometer. The absorbance she reads is 0.262. What is the absorbance of the original undiluted cola, assuming there is no chemical reaction during dilution?

a) 0.0655

b) 0.524

c) 0.131

d) 0.262
