Question

The boiling point of ethanol is 78.40 c. A student conducts an experiment and finds a boiling point at 75.70 c. What was the percent error? (Please show work I have no idea how to do this cause we haven't learned it yet)

Answer 1

`\% \: error = | (origina - expirimental)/(original) | * 100 \\ | (78.40 - 75.70)/(78.40) | * 100 \\ = (2.7)/(78.4) * 100 \\ =3.44 \\ thank \: you`

Answer 2

Erm I did this and got a negative value
