3) Moles of KHP = mass/molar mass
= 0.46/204.23 = 0.00225
7) Molar concentration = moles of NaOH×1000/volume (in ml)
Moles of NaOH = moles of KHP
For all trails :
molar concentration = 0.00225×1000/19.3 = 0.12 M
8) Average molar concentration = 0.12 M
9) Standard deviation = 0
10) Relative standard deviation = 0
