Chemistry Lab Homework: Reaction Rates & Concentration Calculation

Click For Summary
SUMMARY

The discussion focuses on calculating the concentration of acetic acid (CH3COOH) in a chemistry lab setting. The user is attempting to determine the concentration using the formula c = n*v, where n represents moles and v represents volume. The provided information states that vinegar contains three percent acetic acid by weight, which is crucial for calculating the mass (m) needed for the concentration formula. The user must clarify the volume of acetic acid used in the experiment to proceed with the calculations.

PREREQUISITES
  • Understanding of molarity and concentration calculations
  • Familiarity with the formula n = m / M
  • Knowledge of the ideal gas law and its applications
  • Basic understanding of acetic acid and its properties
NEXT STEPS
  • Research the calculation of molarity using mass and volume
  • Learn about the properties and concentration of acetic acid in vinegar
  • Study the ideal gas law and its relevance to chemical reactions
  • Explore practical applications of concentration calculations in laboratory settings
USEFUL FOR

Chemistry students, lab technicians, and educators involved in teaching reaction rates and concentration calculations in laboratory experiments.

Homework Statement


Hello all, I am doing this lab http://scc.scdsb.edu.on.ca/Students/onlinecourses/Sikora/sch4u/v12/60.pdf

i am stuck on trying to find hte concentration of ch3cooh

Homework Equations


n = m / M and c = n*vand i think the ideal gas law could be used but not sure

The Attempt at a Solution


so the volume of ch3cooh for the first trial is 0.02L, and in order to find the concentration i must find the moles

concentration of ch3cooh
If you are told "vinegar" is three per cent acetic acid by weight, does that help?

You're going to have to tell us what these letters mean; we aren't mind readers.

Twenty milliliters of vinegar at three per cent? Or twenty milliliters of acetic acid?
