i am trying to find the molarity of naoh in a titrimetric
determination of KHP.i had four trials. mass of khp are
.7488g,.7361g,.8146g,.7329g. volume of naoh are
19.3ml,19.2ml,21.0ml,19.0ml. i also need the average-M. standard
deviation with a 90% confidence interval. i need the mass of KHP in
unknown. the mass of the unknown are 1.0974g,1.624g,1.0753g,1.0473g.
the volume of naoh for this trial was 7.7ml, 7.9ml,8.0ml,7.7ml. i need
the average %KHP and standard deviation with a 90% confidence
interval. thank you.
