25cm3 of sodium hydroxide react with 17cm3 of 0.1M of H2SO4.
Calculate the molarity of the sodium hydroxide.
The balanced equation is 2NaOH + H2SO4 ---->Na2SO4 + 2H2O.
so the ratio of the ............. NAOH to H2SO4 is 2:1 :D

1cm^3 = 1mL =0.001 L

M=mol/L

So you have 0.1M sulfuric acid, and 0.017L of it. n=MV where M is molarity, n is number of moles and V is volume in Liters

You get 1.7x10^-3 moles of H2SO4.

So to neutralize that, you need twice as many NaOH's, so you need 3.4x10^-3 moles of NaOH to exist in that 0.025 L of solution:

M=n/V=3.4x10^-3 mol/ 0.025L = 0.136M solution of NaOH

Yes I can do Chemistry calculations and you should do your own homework. Talk to your teacher or professor/TA about how to do it and you will learn a whole lot more than if we just give you the answer.

No, I can't do chemistry.
