Wist volume imll of a stock solution pregared by dksolving 4.149g of CuCl22H2O in 1000mik, 15 meeded to mahe 50.00mL. of a 0.1213MCuCl22H2O soluticn? Give your answer to two decimal places. Do not enter units. 2. 2 points Calculate the exact mofarity (M) of a solution that is prepared froin a stock solution of o.5222 M CuCl 2H2O if 33.16mL of this solution is diluted to a fioal volume of 50.00mL. Give your answer to four places after the decimal. Do not enter units. 3 ( 3 sainits. What is the molar absorptivity, e, for CuCl22H2O if the calibration curve (absorbunce A vs concentration (M) gave a best fit line of A=9.04[CuCl22H2O] and the cell path length is b=1.00cm ? Report your answer to two places after the decimal. Do not enter units. A. 1.2172-g sample of a copper unknown was dissolved in water and diluted to a final volume of 100.0mL. The sample was analyzed using a UVIVIS spectrophotometer and the absorbance was found to be 0.443. The calibration curve gave a best fit line of A=8.85M. Calculate the ex(wiw) Cuin thesample. Give your answer to one place after the decimal. Do not enter units
