Solution: How many significant figures are in each of the following measurements?35.0445 g


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

35.0445 g


In this problem, we are asked to determine how many significant figures are in 35.0445 g.

Recall that in determining the number of significant numbers, we following 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.
