Perform the following calculations with the correct significant figures. Show your initial, calculator answer and your final answer. Example: 2.50 cm * 4.00 cm = 10 cm^2= 10.0 cm^ 2 or 1.00 * 10^1 cm^2 A) 3.182 cm * 0.503 cm = B) 0.1567 g + 2.10 g + 1.203 g = C) 8.109 mL – 2.13 mL = D) 9.843 g/2.35 mL =

A) 1.60. cm².

B) 3.46 g.

C) 5.98 mL.

D) 4.19 g/mL.

Explanation:

Hello,

In this case, considering that the result is displayed by showing the same significant figures that the shortest number has and considering the eventual rounding when the next number is greater than 5, we obtain:

A) 3.182 cm * 0.503 = 1.600546 cm² but the number is shown with three significant figures (same as 0.503): 1.60 cm².

B) 0.1567 g + 2.10 g + 1.203 g = 3.4597 g but the number is shown with three significant figures (same as 2.10 g): 3.46 g.

C) 8.109 mL – 2.13 mL = 5.979 mL but the number is shown with three significant figures (same as 2.13 mL): 5.98 mL.

D) 9.843 g/2.35 mL = 4.188511 g/mL but the number is shown with three significant figures (same as 2.35 mL): 4.19 g/mL.

Regards.
