Question

A student calculates the density of an unknown solid. The mass is 10.04 grams, and the volume is 8.21 cubic centimeters. How many significant figures should appear in the final answer?

(1) 1 (3) 3(2) 2 (4) 4

Answer 1

10.04(g) has 4 significant figures, 8.21(cm^(3)) has 3 significant figures.

Since 3<4, we take the fewer one, which is 3.

Therefore, there should be 3 significant figures in the final answer.

Hope this would help~
