Question

EV = 2.8 g/cm3

TV = 2.702 g/cm3

The accuracy of a measured value, such as a melting point, may be evaluated by a calculation of percent
error. Percent error is a common way of reporting how close a measured experimental value (EV) is to
the true value (TV):
EV - TV |
TV
Accurate measurements will typically have low percent errors of <5%.
Percent Error =
×100
