While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water.

What else can I help you with?
How dense is helium compared with air?
Which is more dense: water or helium? - Water is more dense, because water does not float like helium does. It is below air. That's why we have oceans and lakes and rivers.
Is water the least dense than all the liquids?
No. Several liquids, including gasoline, oil and alcohol, are less dense.
Gas that is less dense than air?
Helium is a gas that is less dense than air. This is why a balloon filled with helium rises when released.
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
What are three substances that have a lower density then water?
Ice Air is less dense than water, so water sinks below air. A rock is more dense than water, so it sinks in water and air. And helium, which is less dense than air, rises in air and in water.
Is helium less dense than water?
Yes, it is true.

No. Several liquids, including gasoline, oil and alcohol, are less dense.
Does helium float or sink in water?
Helium gas is less dense than air, so it will rise and float in both air and water.

How does liquid affect the height of which some objects float or sink?
Floating and sinking is related to density - if something is more dense (i.e. has more mass per volume) than the fluid it will sink, and if it is less dense then it will float. This is why wood floats in water, and helium balloons float in air - helium is less dense than air and wood is less dense than water. Steel ships float because, although they are made of steel which is more dense than water, the air inside them is less dense than water so the overall effect is floating.

Is helium a less dense item?
Yes. Helium is lighter than air.
Why is a 1 liter balloon filled with helium is less dense than 1 liter balloon filled with nitrogen?
Better check on that again, helium is lighter than air and the specific gravity of air is approximately 1.3 milligrams per cubic centimeter. Water weighs much more than air, 1 gram per cubic centimeter.
Why a balloon filled with helium floats in air?
Helium is less dense than air
What floats on air?
helium balloon because helium is less dense than air
