mass percent, M, m, X of WHAT? You want us to do 16 of these of just one? Don't you already have the M? Do you need the density?
For H^+, M x L = moles H^+.
moles H^+ x atomic mass = grams H.
%H = (mass H/mass sample)*100 = ??
Note: since the concn of H^+ is so low, the mass of the solvent and mass of the soln is essentially the same and you don't need the density. I also assume the density of the soln is 1.00 g/mL.
I have 93.954 mL of a generic cola solution. The solution contains:
Molarity of H++1.005e-7
Molarity of OH- = 1.005e-7
Molarity of Sucrose(aq) = 6.386e-1
Molarity of Dye= 5.322e-3
Calculate the mass percent, molarity, molality and mole fraction.
