I assume the 0.145m is a typo and you meant 0.145 M. Also I assume you meant NaOH and not naoh which means nothing to me.
2NaOH + H2SO4 ==> Na2SO4 + 2H2O
mols H2SO4 = M x L = ?
Using the coefficients in the balanced equation, convert mols H2SO4 to mols NaOH. That's mols NaOH = 2 x mols H2SO4.
Then grams NaOH = mols NaOH x molar mass NaOH.
