I'm having Sig fig troubles. What would 0.98*2040 be using Sig fig rules???

To determine the answer to your question using significant figures, you need to consider the rules for multiplication and division:

1. When multiplying or dividing numbers, the result should have the same number of significant figures as the measurement with the fewest significant figures.

Let's break down the multiplication of 0.98 and 2040:

0.98 * 2040 = 1999.2

Now, let's consider the significant figures:

0.98 has two significant figures, and 2040 has four significant figures. According to the rule mentioned above, the result should have two significant figures, which is determined by the measurement with the fewest significant figures (0.98 in this case).

Therefore, the answer, considering significant figures, would be 2000 (rounded to two significant figures).
