A nitric acid solution is neutralized using sodium hydroxide. How many grams of sodium hydroxide are needed to neutralize 5.50 L of 1.200 M nitric acid solution?
HNO3 (aq) + NaOH (aq) → H2O (l) + NaNO3 (aq)
How many moles HNO3 do you have? M x L = moles.
Using the coefficients in the balanced equation, convert moles HNO3 to moles KOH.
Then moles KOH = grams KOH/molar mass KOH; solve for grams KOH.
