Question

Solve for the following using the correct number of significant figures.

49.59 g + 15.7 g = _________

Answer 1

To solve the problem, add the given values and round the final answer to the tenths place.

Step-by-step explanation:

To solve the problem using the correct number of significant figures, we need to add 49.59 g and 15.7 g.

First, we identify the least precise number, which is 15.7 g with 3 significant figures. Next, we perform the addition:

49.59 g + 15.7 g = 65.29 g

Finally, we round the final answer to the least precise measurement, which is the tenths place in this case:

65.29 g rounded to the tenths place is 65.3 g.
