I think you mean to say density. If I'm right, it'll sink.
3.5 gml is not a measure of mass, so there can be no such substance.
If an object placed in water sinks - then it has a density greater than water.
It equals the mass of the object placed in it.
If inserted into the water as a solid "blob" then it will sink - unless it dissolves first. But, if because of the shape, the mass of water displaced by whole object is greater than the mass of the object, it will float - just as ships made of metal do.
it will float
The same as when it is in air, unless the object interacts with either water or air, or both (in different ways). Density is dependant on the object's mass and volume and has nothing to do with the medium in which it is sitting, unless that medium interacts with it in some way.
It will sink when the object is placed in water.
We both know it floats
Most likely, the object will be suspended, that is, stay in the middle of the water.
The object will dissolve in the container of water.
The object will sink because the object is denser than water.

Higher than what ?? If the object's density is higher than the density of water, then the object sinks in the water.
If an object placed in water sinks - then it has a density greater than water.
