Answer 1

a) 230.3. The answer in sig fig is 230.3.

Step-by-step explanation:

When performing multiplication or division with numbers, the result should have the same number of significant figures as the quantity with the fewest significant figures. In the given problem, (27.2 x 15.63) / 1.846 = 230.3011918. Since 27.2 has three significant figures, the answer should also have three significant figures.

Rounding the answer, we get 230.3 (option a) as the correct answer.
