What is the formality of a #1.24*g# mass of #"copper sulfate pentahydrate"# in a #100*cm^3# volume of solution? Chemistry Solutions Molarity 1 Answer anor277 Apr 7, 2017 Answer: #"Formality"# #=# #"Moles of solute"/"Volume of solution (L)"=0.05*mol*L^-1#. Explanation: #"Concentration of sodium thiosulfate pentahydrate:"# #-=# #((1.24*g)/(248.18*g*mol^-1))/(100*cm^3xx10^-3*cm^-3*L)# #=0.0500*mol*L^-1# WITH RESPECT TO THE PENTAHYDRATE.
