Interpretation Introduction

(a)

Interpretation:

The maximum uncertainty needs to be calculated, if 1.2-V is digitized with the same three ADCs and input signal is not amplified.

Concept introduction:

Digitization process is defined as conversion of any analog information into a digital form. This digital form can be named as any digitization process of electronic devices and computer systems. The information can be in the form of text, voice, image or sound which is then converted into a binary code. The information in the digitized form is easier to store, transmit or access.

Interpretation Introduction

(b)

Interpretation:

Need to calculate maximum uncertainty, if 1.2-V is digitized with the same three ADCs and input signal is amplified by 10 to bring to full scale.

7) A 25.0 ml sample containing Cu gave an instrument reading of 23.6 units (corrected for a blank). When exactly 0.500 ml of 0.0287M Cu(NO3)2 Was added to the solution,the signal increased to 37.9 units. Calculate the molar concentration of Cu" in the sample +2,
3) The solution taken from a factory waste sample to prepare an internal standard contains Pb + 2 and Ag + 2, and the analysis peaks were determined as 298 mAU and 324 mAU. To analyze the unknown, a solution containing 0.150 M, 50.0 mL of Ag + 2 is put into the unknown liquid and completed to 100.0 mL. When the peaks are measured again, 670 mAU and 856 mAU signals are read from the samples. What is the concentration of Pb + 2 in the unknown liquid?
(B) A 0.05 mM solution of DCPIP was placed in a 1 cm spectrophotometer cuvette and a beam of light at 600nm was passed through the cuvette. The extinction coefficient for DCPIP is 3500 L/mole/cm under the specific conditions used. What proportion (as a percentage) of light would emerge from the other side of the cuvette?
