🤓 Based on our data, we think this question is relevant for Professor Goodwin's class at HCC.
Establish the rules in operations and significant figures and apply them to the given calculation:
43 g + 1.00 g - 2.008 g = 41.992 g
Remember the rules for the significant figures in calculations.
1. For multiplication and division, measurement with the least number of significant figures shall determine the final answer.
2.55 x 5.2 = 13.26
→ since 5.4 has the least significant figures of 2 (2.55 has three), the answer would be rounded up to 13 to retain the significant figures.
A calculator is used to add and subtract measured masses: 43 g + 1.00 g - 2.008 g = 41.992 g What should the numeric answer be when expressed to the correct number of significant figures?
