For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Nonpolar substances are likely to dissolve in nonpolar solvents. For example, nonpolar molecular substances are likely to dissolve in hexane, a common nonpolar solvent.
The complete balanced chemical reaction for this would be:
<span>NaOH + C3H6O3
--> NaC3H5O3 + H2O</span>
So we see that exactly 1 mole of NaOH reacts with 1 mole
of lactic acid.
Calculate moles of NaOH.
moles NaOH = 0.07 moles/L * 0.0268 L
moles NaOH = 1.876 x 10^-3 mol
So,
moles C3H6O3 = 1.876 x 10^-3 mol
The molar mass of lactic acid is 90.08 g/mol so the mass
is:
mass C3H6O3 = (1.876 x 10^-3 mol) * 90.08 g/mol
<span>mass C3H6O3 = 0.169 g</span>
