Answer:
5.68 × 10⁴ mL = 56.8 L
Explanation:
Volume is defined as the amount of three-dimensional closed space. The SI unit of volume is cubic metre which is denoted by the symbol m³.
According to the metric system, other units of volume include: litre (L), millilitre (mL) and cubic centimetre (cm³).
Since, 1 mL = 0.001 L = 10⁻³ L
Therefore, 5.68 × 10⁴ mL = 5.68 × 10⁴ × 10⁻³ L = 5.68 × 10 L = 56.8 L
5.68 × 10⁴ mL = 56.8 L, has three non-zero significant figures.
