Identify the letter of the choice that best completes the statement or answers the question. When determining the number of significant digits in a measurement. When determining the number of significant digits in a measurement,
a. all zeros are significant.
b. all nonzero digits are significant.
c. all zeros between two nonzero digits are not significant.
d. all nonzero digits are not significant.
According to the rule of significant figures;
- <em>all nonzero digits in a number are significant. For example, 161.45 has 5 significant digits. </em>
- <em>all zeros after nonzero digits without decimal points are not significant. For example, 12300 has 3 significant digits.</em>
- <em>all zeros located between nonzero digits are significant. For example, 2002 has 4 significant digits.</em>
- <em>leading zeros in a digit are not significant. For example, 00123 and 0.0123 have 3 significant digits each. </em>
Hence, the correct option is B.
