Solve the following , observing significant figure rules 110.10g+13g+0.656g square g

To solve the problem while observing significant figure rules, we need to consider the number of decimal places in each measurement.<br /><br />1. \(110.10 \, \text{g}\) has two decimal places.<br />2. \(13 \, \text{g}\) is a whole number with no decimal places.<br />3. \(0.656 \, \text{g}\) has three decimal places.<br /><br />When adding numbers, the result should be rounded to the least number of decimal places present in any of the numbers being added. In this case, that is zero decimal places (from the \(13 \, \text{g}\)).<br /><br />Now, let's perform the addition:<br /><br />\[ 110.10 \, \text{g} + 13 \, \text{g} + 0.656 \, \text{g} = 123.756 \, \text{g} \]<br /><br />Since we need to round to the nearest whole number (zero decimal places), the final answer is:<br /><br />\[ 124 \, \text{g} \]
