ÎH melt (molar enthalpy of melting): 36,65 kJ/mol ÎH° 298 (Standard molar enthalpy of reaction at 298 Ð): -1433,7 (s) kJ/mol ÎG° 298 (standard molar Gibbs energy of reaction at 298 Ð): -1316,4 (s) kJ/mol S° 298 (standard molar entropy at 298 Ð): 175,7 (s) J/(molâ¢Ð) C° p (standard molar heat capacity): 130,1 (s) J/(molâ¢Ð) Surf. Molar mass calculator computes molar mass, molecular weight and elemental composition of any given compound. â¢ KHSO4 + KOH = K2SO4 + H2O A mole is an amount, refers to Avogadros number which is 6.022 x 1023. a mole of atoms is that many atoms. in a 3.75 molal solution you have 3.75 moles in 1 kg of solvent. What is the concentration of SO42â ions in the solution? Chemistry. A chemist makes a solution of K2SO4 by dissolving 21.8 g K2SO4 in water to make 100.0 mL of solution. grams = 58.443 × 5 = 292.215 (g) A saline solution with a mass of 400 g has 30 g of NaCl dissolved in it. To answer this question one needs to recall what the definition of molality is. Menu. Recall that M is equivalent to mol/L. Iron(II) Sulfate FeSO4 Molar Mass, Molecular Weight. moles of KMnO 4 = 23.7 g KMnO 4 x (1 mol KMnO 4 /158 grams KMnO 4) moles of KMnO 4 = 0.15 moles KMnO 4; Now the liters of solution is needed. The units are mol/kg. Molar mass calculator computes molar mass, molecular weight and elemental composition of any given compound.
