Solution: How many significant figures are in each of the following measurements?0.03003 kg

Problem

How many significant figures are in each of the following measurements?

0.03003 kg

Solution

In this problem, we are asked to determine how many significant figures are in 0.03003 kg.


Recall that in determining the number of significant numbers, we follow the following rules:

  • All nonzero digits are significant.
  • Zeroes between nonzero digits are significant.
  • Zeroes to the left of the nonzero digits are not significant, their only purpose is to indicate placement.
  • Zeroes to the right of the nonzero digits are categorized as follows:
    • Trailing zeroes after a decimal point are significant.
    • Trailing zeroes before the decimal point and after a nonzero digit are always significant.
    • Trailing zeroes before an implied decimal point is ambiguous and should be avoided by using scientific notation.
