6.853g of sodium cyanide was dissolved in water and brought to volume in a 100ml volumetric flask. The final mass of the solution was found to be 107.166g
My understanding -
A solution is understood when I put a solute into a solvent (water) and dissolves it.
So in this case, if I wanted to find the composition of solution expressed as moles, I must take mass multiply by the molecular weight of Sodium Cyanide, do I use the mass of the solution or the mass of solute ?
With this then I can go on to find molarity, normality as well as weight percent (mass of solute/mass of total solution) and weight/volume percent (mass of solute/volume of total solution).
