Determine the volume in milliliters of a 0.162 M NaOH solution needed to neutralize a 235 mL solution of 0.108 M HCl and 0.216 M H2SO4.

PLEASE HELP ME, I DON'T KNOW WHAT I AM DOING WRONG, I HAVE TWO ATTEMPTS LEFT PLEASE
157, 470, 235, 940, 156, and 313 (mL) are all wrong :(( idk why help please!

it was 782 mL. you add 156 + (313 x2) =782, the 156 and 313 are from mv=mv. 313 is multiplied by two bc 2NaOH+H2SO4⟶Na2SO4+2H2O, so it reflects the moles i think

The original problem is not stated properly. You need to know what part of that 235 mL is NaOH and how much is H2SO4.
