0.102 x 0.0821 x 273 / 1.0

what can i express this in the correct number of significant figures ?@_@

two. The 1.0 dictates 2.

(0.102)(0.0821)(273)/(1.01)

To determine the correct number of significant figures, follow these steps:

1. Identify the number with the fewest significant figures, which is 1.0 in this case.

2. Apply the same number of significant figures throughout the calculation.

So, to express the result in the correct number of significant figures, use 1 significant figure:

0.102 x 0.0821 x 273 / 1.0 = 2.180614

Rounded to 1 significant figure, the final result is 2.

To express the result of a calculation with the correct number of significant figures, you need to follow the rules of sig figs. The general rule is that the result should have the same number of significant figures as the measurement with the least number of significant figures that you used in the calculation.

Let's break down the calculation step by step to determine the number of significant figures:

0.102 x 0.0821 = 0.0083942 (The least precise measurement here is 0.0821, which has 4 significant figures.)

Now we multiply the above result by 273:

0.0083942 x 273 = 2.2916646 (Since 273 is a whole number, it does not affect the number of significant figures.)

Lastly, we divide the result by 1.0:

2.2916646 / 1.0 = 2.2916646 (Dividing by a whole number also does not affect the number of significant figures.)

Now, we need to express the result using the correct number of significant figures based on the measurement with the least number of significant figures. In this case, 0.0821 has 4 significant figures, so we round the final result to 4 significant figures:

2.2916646 ≈ 2.292

Therefore, the correctly expressed result with the appropriate number of significant figures is approximately 2.292.
