Q1) A solution of ascorbic acid (C6H8O6, Formula mass = 176 g/mol) is made up by dissolving 80.5 g of ascorbic acid in 210 g of water, and has a density of 1.22 g/mL at 55 oC. Calculate the following:

a) the mass percentage of ascorbic acid
b) the mole fraction of ascorbic acid
c) the molality of the solution
d) the molarity of ascorbic acid in this solution

    You do most of this the same way I worked the first problem for you. Just remember the de4finitions.
    mass% = (mass X/total mass)*100 = ?
    X = (moles X/total moles)
    molality = m = moles X/kg solvent.
    M = molarity = moles/L soln.
