Question

Simon measured the density of a piece of metal
to be 11.70 g/cm³. However, the manufacturer
claims it has a density of 12.00 g/cm³. What is
the percent error of Simon's measurement?

Answer 1

From the question we know that 12 - 11.70 = 0.3  so 0.3 / 12 = 0.025 therefore Simon's percent error is 2.5%.

Percent error compares an estimate to an accurate value and expresses the difference among them as a percent. This statistic lets analysts recognize the scale of the mistake relative to the true cost. it's also referred to as percentage error as well as % mistakes.

Percentage errors Calculation Steps :

• Subtract one cost from another.
• Divide the mistake by the exact or ideal price (not your experimental or measured value).
• Convert the decimal variety into a percentage by multiplying it by using 100.

• Add a percent or % symbol to record your percentage mistakes value.

Percentage error tells you the way huge your mistakes are when you degree something in an experiment. Smaller values suggest that you are close to the accepted or actual value. for instance, a 1% blunder means that you obtain very near the accepted value, whilst 45% means that you were pretty a long way off from the real value.
