A solution of hydrogen peroxide is 24.26% by mass and has a density of 1.11g/cm^3. the molarity of the solution?
7.54M
.273M
8.03M
8.37M
none of these

    Take a liter of the stuff.

    then mass is 1110 grams, of which 269 grams is H2O2.

    Molarity= 269/(molmassH2O2*1)

    The closest is the third. Check my math.
