Question

The accepted value of assay is 10 g, while the result is 9.8 g. What is the relative error?

• A. \( 0.02 \)
• B. \( 0.2 \)
• C. \( 2.0 \)
• D. \( 20.0 \)

Hint:

Remember: Relative error compares the error to the true value. It's (your mistake) / (the right answer).

Answer 1

The Correct Option is A

The relative error is the absolute error divided by the accepted value. Absolute error = |Experimental value - Accepted value| Absolute error = |9.8 g - 10 g| = |-0.2 g| = 0.2 g Relative error = (Absolute error / Accepted value) Relative error = (0.2 g / 10 g) = 0.02 The relative error is often expressed as a percentage by multiplying by 100: Relative error (%) = 0.02 * 100 = 2% However, the options are given as decimal values, so the relative error is 0.02.
