Question

Percentage Error of water (density, mass, volume, and slope)?
We did testing on water and I don't know how to do percentage error!

Water Volume in mL:
5
10
15
20
25

Water Mass in g:
4.52
8.28
14.28
19.26
24.7

Mass Volume Ratio was .940.
I'm not sure how to do the slope. I don't know how to take the percentage error! How do I find the Accepted Value and the Experimental Value?
Please and thank you to all who help!

Answer 1

Percentage error is\[\frac{ (experimental Value - acceptedValue) }{ accepted Value }\times100\]
You will have to search up the accepted value, and calculate the experimental value.

Answer 2

the slope is your mass/volume ratio when you plot mass vertically and volume horizontally.

Your experimental answer is the slope of the line that your data creates.
