When we assume that our solvent is water with total weight 100 g:
so we need to get the mass of K2SO3:
mass of K2SO3 = moles K2SO3 * Mw of K2SO3
now we need to get first the Mw of K2SO3 = 2*39 + 1*32 + 3*16 = 158 g/mol
by substitution:
∴ mass of K2SO3 = 0.0328 moles * 158 g/mol = 5.18 g
∴the mass of water = 100 g - 5.18 g = 94.8 g
∴ moles of water = mass of water / Mw of water
= 94.8 g / 18 g/mol
= 5.2 moles
∴the total moles = moles of water + moles of K2SO3
= 5.2 + 0.0328 = 5.266 moles
∴ the weight/weight % of K2SO3 = moles of K2SO3 / total moles*100
= 0.0325 moles / 5.266 moles *100
= 0.0062 *100
= 0.62 %
During the evaporation process, liquid components separates from the solid components
Evaporation process means the change liquid water to gaseous water called evaporation and during evaporation process the soluble solid can be separated from its liquid component by allowing the liquid component to evaporate either by its own or by heating and also during evaporation the liquid component is lost to the atmosphere and the solid remains behind
