A student determined the heat of fusion of water to be 366.9 J/g. If the accepted value is 333.3J/g, what is the student's percent error?
A. 8 %
B. 10 %
C. 15 %
D. 30 %
Per cent of error is found by subtracting the accepted value from the calculated value, dividing by the accepted value and then multiplying by 100.
Calculated value - accepted value / accepted value x 100 =
366.9 - 333.6 / 333.6 x 100 = 33.3 / 333.6 x 100 = 10%
