Question #7e0de Chemistry Solutions Molarity 1 Answer Michael Apr 22, 2015 93.12g #c=n/v# Where: #c# = concentration #v# =volume #n# = no. moles So: #n=cv# #n= 0.5xx2.5 = 1.25# #M_r[KCl]=(39+35.5)=74.5# So 1 mole weighs 74.5g So 1.25 mol weighs #1.25xx74.5 = 93.12"g"# (Approx #A_r# values used) Answer link Related questions what is the molarity of 20.0 ml of a KCl solution that reacts completely with 30.0 ml of a 0.400...
