Step-by-step explanation:
- A substance will floats if it is having lower density than the density of the liquid in which it is placed.
- A substance will sink if it is having density greater than the density of the liquid in which it is kept.
Density of corn syrup =

1) Density of gasoline =

Density of the gasoline is less than the the density of corn syrup which means it will float in corn syrup.
2) Density of water =

Density of the water is less than the the density of corn syrup which means it will float in corn syrup.
3) Density of honey =

Density of the gasoline is more than the the density of corn syrup which means it will sink in corn syrup.
4) Density of titanium =

Density of the titanium is more than the the density of corn syrup which means it will sink in corn syrup.
