A mixture contains 21.7 g NaCl, 3.74 g KCl, and 9.76 g LiCl. what is the mole fraction of NaCl? Chemistry 1 Answer anor277 Apr 19, 2018 #chi_"NaCl"=0.570# Explanation: #chi_"NaCl"="Moles of sodium chloride"/"Total moles of all the salts."# #=((21.7*g)/(58.44*g*mol^-1))/((21.7*g)/(58.44*g*mol^-1)+(3.74*g)/(74.55*g*mol^-1)+(9.76*g)/(42.39*g*mol^-1))# #0.371/0.652=0.570# If you work out #chi_"KCl"# and #chi_"LiCl"#...the sum of the mole fractions of each component should equal WHAT?
