Step 1

We have to determine the number of significant figures in the given measured quantities-

  1. 351 g
  2. 0100 mL
  3. 010 mL
  4. 75×10-3cm
Step 2

Significant figures are the digits of a number that are important to express the accuracy and the precision of that number.

Rules to identify the significant figures-

  1. All non-zero digits are significant.
  2. Any zero between two significant digits are also significant
  3. Only trailing zeros in decimal portion are significant.
