Explanation:

Part C:

Step 1: Identify the first three significant figures

The number is 44.981 g. The first three significant figures are 4, 4, and 9. The next digit is 8, which is greater than 5, so we round up the third significant figure.

Step 2: Round the number

The third significant figure is 9. When we round up 9, it becomes 10, so we carry over the 1 to the second significant figure. The second significant figure (4) becomes 5, and the third significant figure becomes 0. So the number rounded to three significant figures is 45.0.

Answer:

45.0
