Your density.
Taking a deep breath helps you float in water because it increases the volume of air in your lungs, making your body more buoyant. This increases your overall buoyancy and helps you stay afloat in the water.
Taking a deep breath while in water will make a person more buoyant, causing them to float with more of their body out of the water. This is because the volume of air in the lungs increases, creating more lift.
When you breath out under water, you are releasing the air from your lungs. Air is far less dense than water, which is why things that are filled with air float. So if you breath in, and then go under water you will float toward the surface. However, if you breath out and release that air in your lungs, you lose the buoyancy that the air was giving you. Thus causing you to sink...

Sparkling water contains carbon dioxide gas that creates bubbles. These bubbles attach to objects, making them buoyant and causing them to float. The bubbles decrease the density of the water, allowing objects to float more easily.

A bar of soap floats in water because it is less dense than water. The air pockets and ingredients in the soap decrease its overall density, allowing it to float on the surface of the water.
Old eggs float because as they age, the air cell inside the egg grows larger. This causes the overall density of the egg to decrease, making it more buoyant and likely to float in water.
To lower the toilet tank water level in your bathroom, you can adjust the float valve inside the tank. This can usually be done by turning a screw or adjusting a knob on the float valve mechanism. By lowering the float, you can decrease the amount of water that fills the tank after each flush.
A rock with lots of tiny holes can float because these holes decrease its density, making it less heavy than the same amount of water it displaces. This reduced density allows the rock to overcome gravity and float on the surface of water.
A rock could float if its density is less than that of water, as is the rock pumice, or if it is shaped in a manner that would displace an amount of water to sufficiently cause it to float when carefully placed in water.
Pears do not float in water because the pear is more dense than the water. The pear has a high water content, therefore making it more dense. For example, apples float because they are less dense than the water.
