Question

If vinegar is actually 5.00% by mass acetic acid in water, what is your percent error?( percent error =[ actual value- experimental value/actual value]) *100

Answer 1

To calculate the percent error, we first need to determine the actual value and the experimental value.

The actual value is given as 5.00% acetic acid in water.

The experimental value is the percent of acetic acid measured in the vinegar sample.

Let's assume we measured the vinegar sample and found it to be 4.75% acetic acid in water.

Now we can calculate the percent error:

Percent error = [(5.00 - 4.75)/5.00] * 100
Percent error = [0.25 / 5.00] * 100
Percent error = 0.05 * 100
Percent error = 5.00%

Therefore, the percent error is 5.00%.
