According to the following reaction, how many grams of tetraphosphorus decaoxide are required for the complete reaction of 26.5 grams of perchloric acid (HClO4)?

perchloric acid (HClO4) (aq) + tetraphosphorus decaoxide (s) ---> phosphoric acid (aq) + dichlorine heptaoxide (l)


_____ grams tetraphosphorus decaoxide

The equation is not complete.
P4O10 + 2HClO4 + 5H2O ==> 4H3PO4 + Cl2O7

mols HClO4 = grams/molar mass = ?
mols P4O10 = 1/2 mols HClO4
g P4O10 = mols x molar mass = ?
Poat your work if you get stuck.
