We have #15xx0.2=3.0mmol# reacting with #10xx0.15=1.5mmol#

Explanation:

So the mol ratio is #3.0div1.5=2#

Since phosphoric acid does not easily give off its third proton, and if the hydroxide were sodium hydroxide, the most likely equation would be:

#2NaOH+H_3PO_4->Na_2HPO_4+2H_2O#

Or: #2OH^(-)(aq) +H_3PO_4(aq)->HPO_4^(2-)(aq) +2H_2O(l)#

With (di)sodium (mono)hydrogen phosphate as the resulting salt.
