<em>Isn't that going to be an D since 1 foot is equal 12 inches.</em>
First convert mass to number of moles. Molar mass
of H2C2O2 • 2H2O = 94 / mol
1.89g / (94 g / mol) = .02 mol H2C2O2 • 2H2O
Then we divide by 0.1 L, or 100 mL, and we get a
concentration of 0.2 M.
Since there are two positive ions (2 H+), therefore
normality is:
