What is the concn of WHAT? in mass percent?
Psoln = Xsolvent*Psolvent
81.1 = Xsolvent*(92.6)
Solve for X which is the mole fraction of the solvent,
1-mole fraction solvent = mole fraction solute.
Convert mole fraction solute to mass percent.
Psoln = Xsolvent*Psolvent
81.1 = Xsolvent*(92.6)
Solve for X which is the mole fraction of the solvent,
1-mole fraction solvent = mole fraction solute.
Convert mole fraction solute to mass percent.
