हिन्दीWhen experimental data are subtracted, such as \( 12.9 \text{ g} - 7.06 \text{ g} \), according to the rules of arithmetic operations with significant figures, the result should be reported to:
Correct answer · Option 2
5.8 g
Explanation
In subtraction or addition, the final result should retain as many decimal places as there are in the number with the least decimal places (\( 12.9 \text{ g} \) has 1 decimal place). Thus, \( 5.84 \text{ g} \) rounds off to \( 5.8 \text{ g} \).
