Interpretation Introduction To determine: Vapor pressure of the solution. Explanation Given: Mass % ( NaCl ) = 5 .50 T = 25°C P H 2 O ° ( 25°C ) = 23 .8 Torr Assumption: NaCl dissociates completely. Explanation: Mass percent of NaCl indicates that 100 g of solution contains 5.5 g of NaCl . Calculate the mass of water in 100 g of solution as follows: m H 2 O = m solution − m NaCl = 100 g − 5 .5 g = 94 .5 g Calculate the number of moles of water as follows: n H 2 O = m H 2 O Molar mass ( H 2 O ) = 94 .5 g 18 .02 g/mol = 5.2442 mol Calculate the number of moles of NaCl as follows: n NaCl = m NaCl Molar mass ( NaCl ) = 5 .5 g 58 .4 g/mol = 0 .0942 mol The reaction for complete dissociation of NaCl is as follows: NaCl ( s ) → Na + ( aq ) + Cl − ( aq ) Complete dissociation of 1 mol of NaCl produces 2 mol of dissolved particles in the solution
