Okay, i seem to have forgotten all my basic chemistry from my 1st year of college. Now im taking up another chemistry subject on my 4th year and i seem to be lost.

I'm asked 'how many moles of H2O(l) were formed in these neutralization reactions:

#1 : 20.0mL H2O + 10.0mL 3M HCL + 10.0mL 1.25M NaOH
#2 : 20.0mL H2O + 10.0mL 3M HNO3 + 10.0mL 1.25M NaOH
#3 : 20.0mL H2O + 10.0mL H2SO4 + 10.0mL 1.25M NaOH

I formed my H2SO4 by adding 5mL of concentrated sulfuric acid and 45mL of water.

For all reactions, i got 0.003mol H2O. I have no idea if i did this correctly
HELP!
