35ml of HCI solution was used to titrate 0.8654g of THAM (molar mass of THAM=121.14 g/mol). What is the exact.?
concentration of HCI? a. 0.1740 M b. 0.2935M c. 2.935 times 10^-4 d. 0.29348

Hi, n(THAM) = m(THAM) / M(THAM) n(THAM) = 0,8654 / 121,14 n(THAM) = 7,14•10^-3 mol of THAM n(THAM) = Ca x Va . . . therefore : Ca = n(THAM) / Va Ca = 7,14•10^-3 / 35•10^-3 Ca = 0,204 mol/L Answered by Yong Privott 1 year ago.
What mass of primary standard THAM should be weighed out to require 40 mL for titration with 0.10 M HCl?
Asked by Dorla Vanputten 1 year ago.
molar mass THAM = 121.14 g/mol moles HCl = 0.10 M x 0.040 L= 0.0040 moles THAM = 0.0040 mass THAM = 0.0040 x 121.14 g/mol=0.485 g Answered by Yuri Falconer 1 year ago.
