Answer #1

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
