Q.8) We know that, Molarity = No. of moles of solute / volume of solution in L
No. of moles of solute = Molarity volume of solution in L
No. of moles of NaOH added to acid solution = [ NaOH ] volume of solution in L
We have, [ NaOH ] = 0.118 mol / L & Volume of solution = 1.71 ml = 0.00171 L
No. of moles of NaOH added to acid solution = 0.118 mol / L 0.00171 L = 0.000202 mol
ANSWER : 0.000202
Q.9 ) Volume of titrant added = Final volume - Initial volume
Volume of titrant added = 1.54 ml - 0.40 ml = 1.14 ml
ANSWER : 1.14
