## Homework Statement

Hello, I missed a lab before the break because I was really sick and I need help. I was given the data from my partners for the titration lab and I don't understand how to calculate the amount of potassium hydrogen phthalate used in each trial, amount concentration of the sodium hydroxide solution and the average concentration of the solution. Thanks in advance.

They used .5g of KHP.

Trials(mL)

1 2 3

Initial volume of NaOH: 0 | 5.8 | 12.2 |

Final volume of NaOH: 5.8 | 12.2 | 17.3 |

Total Volume: 5.8 | 6.4 | 5.1 |

## Homework Equations

c=n/v, n=m/mm c1v1=c2v2

## The Attempt at a Solution

When they say amount do they mean g or moles?

n=m/mm

n=.5/204.22

n=0.002448

Do I use the final volumes to calculate amount concentration?
