In lab, you add 2.052 g salicylic acid to a 125 mL Erlenmeyer flask, as listed in the procedure. You carefully add 4.0 mL acetic anhydride, swirl for a few minutes, then have your TA add 5 drops of sulfuric acid. After completing the synthesis and filtering, you place the crystals to dry on an evaporating dish that weighs 21.592 g. After drying, the crystals and evaporating dish weight 23.473. Calculate the percent yield of aspirin.

Woah that’s a lot to read xd i’ll try though. i’ll get back t you if. i know the andwer

Ibelieve it's celsius. hope this .

  the volume of  0.220 m k2s    solution  required  to  completely  react with 175 ml  of 0.115m co(no3)2  calculate the moles  of co(no3)2 =  molarity x volume/1000175 x0.115/1000= 0.02  moleswrite  the reacting  equationk2s(aq)  +  co(no3)2  = 2 kno3(aq)  + cos(s)by  use  of mole ratio between k2s to co(no3)2 which  is  1: 1 the moles of k2s is therefore = 175  x0.115/1000= 0.02  molesvolume = moles/molarity=0.02/0.22=0.09  ml  of k2s
