Answer:
The correct option is : c) 0.0431 L
Explanation:
Volume is defined as the amount of space occupied by a substance when enclosed in a container. The substance can be present in the solid, liquid, gas, or plasma state. The SI unit of volume is cubic metre (m³).
Another unit of volume included by the metric system is litre (L), where one litre is equal to 1000 cm³.
1 L = 1000 cm³
or, 1 cm³ = (1 ÷ 1000) L = 0.001 L
Therefore,
43.1 cm³ = (43.1 ÷ 1000) L =<u> 0.0431 L </u>
