Given the reaction 2NaOH + H2SO4 = Na2SO4 + 2H2O, what is the total number of grams of NaOH needed to react completely with 196 grams of H2SO4

2 moles of NaOH react with 1 mole of H2SO4

therefore x moles will react with 196 moles (moles can interchange with grams over here)

196 x 2 = 392

so 392 grams of NaOH will be required to react completely with 195 gram of H2SO4
