Explanation:
To determine the product of 0.021 and 0.09330 with the correct number of significant figures, we need to consider the significant figures in each number.
The number 0.021 has two significant figures because there are no non-zero digits after the decimal point.
The number 0.09330 has five significant figures because all the digits are non-zero.
When multiplying or dividing numbers, the result should have the same number of significant figures as the number with the fewest significant figures.
In this case, the number with the fewest significant figures is 0.021, which has two significant figures.
Multiplying 0.021 by 0.09330, we get:
0.021 x 0.09330 = 0.0019563
Since 0.021 has two significant figures, the final answer should also have two significant figures.
Therefore, the answer to the calculation 0.021 x 0.09330, expressed with the correct number of significant figures, is 0.0020.
