You can put this solution on YOUR website!
That would be expected 48% weight per weight. This site, http://www.h2o2.com/technical-library/physical-chemical-properties/physical-properties/default.aspx?pid=11&name=Density-of-H2O2-Solutions, indicates the density is about 1.19 g/ml. That also indicates 1.45 g/ml for 100% hydrogen peroxide.

320 ml. of hydrogen peroxide is 0.32 liter of it.
320%2Aml%2A1.45%28gram%2Fml%29=highlight%28464%2Agrams%29 of hydrogen peroxide.

48%2F100=464%2FS, where S is the mass in grams, of HYDROGEN PEROXIDE SOLUTION, 48%.
-
S%2F464=100%2F48
S=464%28100%2F48%29
highlight%28S=966%262%2F3%2Agrams%29 of 48% solution

To put this into volume, 966%262%2F3%2Agrams%28%281%2Aml%29%2F%281.19%2Agrams%29%29=highlight%28812%2Aml%29, which should be 810 ml, to TWO SIGNIFICANT FIGURES.
