the mass of three samples of granite were measured. what is the total mass, reported to the appropriate number of significant figures?\n14.79 g + 86.2 g + 97.874 g = ? g
Answer
Explanation:
Step1: Add the masses
First, we add the three masses together: (14.79 + 86.2 + 97.874). Let's calculate that: (14.79 + 86.2 = 100.99), then (100.99 + 97.874 = 198.864).
Step2: Determine significant figures for addition
When adding, we look at the number of decimal places. The least number of decimal places among the numbers is 1 (from 86.2). So we round the result to one decimal place. (198.864) rounded to one decimal place is (198.9).
Answer:
(198.9)
