Web12 jun. 2024 · Molar mass of K2SO3 is ( (2x39.098)+ (1x32.06)+ (3x15.999)) g/mol = 158.253 g/mol. So Moles of (K2SO3) = (10.0 g/158.253) mol = 0.0632 mol Now we have to account of the volume of the solution .. Moles of solute (in solution) = 0.0632/100ml x 1L/1000ml = (0.0632 / 0.200) mol = 0.31595 mol Step 2 - Find 'ion-to-solute' ratio Web13 sep. 2024 · 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
