An absorption measurement with a 1 cm path length yields a reading of 0.002 absorbance units with a noise of 0.0005 absorbance units and a mean noise reading of O for 5 scans averaged together. Assuming the noise for a single scan does not change if the path length is increased to 5 cm and the number of scans is increase to 65, what is the signal to noise of the new measurement. Remember signal averaging form the previous module.
