WebThe osmotic pressure of a solution of an organic substance containing 1 8 g in 1 l t of the solution at 2 9 3 K is 2. 4 1 4 × 1 0 5 N / m 2. The molecular mass of the substance if R = … WebΔT = change in temperature. Step 2: Calculate moles of solute (n) n = m ÷ M. n = moles of solute. m = mass of solute. M = molar mass of solute. Step 3: Calculate mount of energy (heat) released or absorbed per mole of solute (ΔH soln) ΔH soln = q ÷ n. ΔH soln = molar enthalpy (heat) of solution.
