Mole fraction of solute in aqueous solution of 30% naoh

Answered by admin @ 20/08/2021

NaOH solution is prepared in water.
Molar mass of NaOH = 40 g
Mass of NaOH = 30 g
Molar mass of water = 18 g
Given mass of water = 70 g
Number of moles of NaOH = 3040 = 0.75 moles
Number of moles of H2O = 7018 = 3.88 moles
Mole fraction of NaOH = 0.75/0.75+3.88
=0.161
