H3PO4 + 3NaOH ==> 3H2O + Na3PO4
mols H3PO4 = 0.4/molar mass H3PO4 = ?
Convert mols H3PO4 to mols NaOH using the coefficients in the balanced equation.
M NaOH = mols NaOH/L NaOH.
You know M and mols NaOH, solve for L NaOH
Calculate the volume of a 0.150 M NaOH solution that will be required to neutralize all of the H+ ions in 0.400 grams of phosphoric acid?
