When subtracting \( 7.06\text{ g} \) from \( 12.9\text{ g} \), the correct result reported with proper significant figures/decimal places is:

  1. \( 5.84\text{ g} \)
  2. \( 5.8\text{ g} \)
  3. \( 6.0\text{ g} \)
  4. \( 5.840\text{ g} \)

Correct answer · Option 2

\( 5.8\text{ g} \)

Explanation

In addition or subtraction, the result should retain as many decimal places as are present in the number with the least decimal places (\( 12.9 \) has 1 decimal place). Hence, \( 5.84 \) rounds off to \( 5.8\text{ g} \).
