When multiplying 3.24 and 2.0, how many significant figures should the result have?

Explanation:
When multiplying numbers, the result can only have as many significant figures as the factor with the fewest significant figures. The first number has three significant figures, while the second has two. Therefore, the product should be reported with two significant figures. The exact product is 3.24 × 2.0 = 6.48, which rounds to 6.5 when limited to two sig figs. So the correct count is two, not four.
