To find the sum of 334.540 g and 198.9916 g, we add the two values together, resulting in 533.5316 g. When considering significant figures, the result should be rounded to the least number of decimal places in the original numbers, which is three decimal places (from 334.540 g). Therefore, the final answer is 533.532 g.
0.1
0.0712 rounded to one significant figure is 0.1. In this case, the first significant figure is the digit '7', but since we only want one significant digit, we round it based on the next digit, which is '1'. Thus, the final answer is expressed as 0.1.
To round 0.874 to 1 significant figure, we focus on the first digit, which is 8. The next digit (7) is greater than 5, so we round up. Therefore, 0.874 rounded to 1 significant figure is 0.9.
23.16492 has seven significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
43.6109 has six significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.

To round numbers to the correct number of significant figures, start by identifying the last significant figure you want to keep. Then, look at the next digit - if it is 5 or greater, round up; if it is less than 5, round down. Finally, adjust the rest of the digits to the right of the last significant figure to zeros.
