Question

How to calculate percent error of a melting point range?

Melting Point Average 122.5°C - 128°C
Literature Melting Point 121°C - 123°C
% Error (melting point)

Answer 1

3.9%

Step-by-step explanation:

Exact melting point = 123°C

Measured melting point = 128°C

% error; |measured - exact|/exact × 100

% error = |123 -128|/128 × 100

%error = 3.9%

Percentage error in temperature measurement = 3.9 %
