In a U-shaped tube (both sides open, placed horizontally), ethanol (SG = 0.80) is contained. When an unknown metal (mass: 20 g) was fully submerged in the ethanol, the liquid level increased by 1 cm. Given that the U-shaped tube has constant diameter of 1 cm, what is most approximately the specific gravity of the unknown metal? 12.74 O 19.45 O 15.91 17.96
