Chloride east.cengagenow.com 2. The student read the molarity of AgNO, as 0.0261 Mad of 0.0216 M. The experimentally calculated moles of Ag would be too the calculated moles of CI would come out too b. The student took the initial buret reading correctly but took the final buret reading from the top of the manicus. The experimentally determined mules of Ag" would be too so the calculated moles of C would come out SA A 10.00 ml diluted chloride sample was titrated with 0.0216 M AgNO, and 17.73 ml. AgNO, was required to reach the endpoint How would the following errors affect the calculated concentration of C Try Aner Version temat ¹ Ⓒ would the calculated C concentration The calculated (C) in the unknown would come out too D V
