Q: Add 17.35 g , 25.6 g and 8.498 g and write the result with the correct number of significant figures .

Sol: Out of three given values 25.6 g is least accurate . Other two values have to be rounded off to one place of decimal i.e. 17.35 ≈ 17.4 g and 8.498 ≈ 8.5 g

Hence , 17.4 + 25.6 + 8.5 = 51.5 g
