WebAug 7, 2024 · Explanation: We want the expression...... molality = moles of solute kilograms of solvent ..... And our H 2SO4(aq) has a density of ρ = 1.2 ⋅ g ⋅ mL−1. And thus we can work with a 1 ⋅ mL volume.......... Molality = 1.2⋅g×27% 98.08⋅g⋅mol−1 (1.2 ⋅ g − 0.324 ⋅ g) ×10−3 ⋅ kg ⋅ g−1 = 3.77 ⋅ mol ⋅ kg−1 with respect to H 2SO4 ...... WebAug 8, 2024 · The molality ( m) of a solution is the moles of solute divided by the kilograms of solvent. A solution that contains 1.0 mol of NaCl dissolved into 1.0 kg of water is a "one-molal" solution of sodium chloride. The symbol for molality is a lower-case m written in italics. Molality ( m) = moles of solute kilograms of solvent = mol kg. WebThe molarity of H 2SO 4 is 18 M. Hence, 1 L of H 2SO 4 corresponds to 18 moles of H 2SO 4. The density of H 2SO 4 is 1.8 g/mL. Thus 1 L of H 2SO 4 corresponds to 1800 g or 1.8 kg. Out of this 18×98=1.764kg corresponds to H 2SO 4. Hence, the mass of water is 1.8kg−1.764kg=0.036kg. Hence, the molality of the solution is 0.03618 =500m. brooke weston sixth form open evening
