Answer:
The object will not float in water because the density of the object is greater than that of water.
Explanation:
Density of object = 1.75 g/mL
Density of water = 1 g/mL
The Density of the object is 1.75 g/mL and that of water is 1 g/mL. This implies that the object is denser (i.e heavier) than water. Therefore, the object will not float in water, rather it will sink in water since it's density is greater than that of water.
