Sorry Dr. Bob, I wsa looking for the Sucrose, not all 16 calculations. Can you help me with the Sucrose?
I have 93.954 mL of a generic cola solution. The solution contains:
Molarity of H++1.005e7
Molarity of OH = 1.005e7
Molarity of Sucrose(aq) = 6.386e1
Molarity of Dye= 5.322e3
Calculate the mass percent, molarity, molality and mole fraction.

DrBob222,
I suppose we assume the density of the solution is 1 (unless you have a density listed).
0.6386 M sucrose is 0.6386 moles/L soln.
grams sucrose = 0.6386 x 342.3 = 218.6g/L soln or 218.6 g sucrose + 781.4g H2O.
If we assume the density of the solution is 1.00 g/mL (and I don't think that will be true) mass percent w/w = 218.6g/1000 g soln or 21.86g/100 g soln = 21.86% w/w.
molality = moles kg solvent = 0.6386/0.7814 = ??
Check my work. I would have been more comfortable with a density.
For X, you convert each of the quantities to moles, then mole fraction sucrose = moles sucrose/total moles.
