Yes, a mole of hydrogen weighs 1 g, a mole of helium weighs 4 g. Still lighter than air, as a mole of air weighs about 30 g.

Why does a helium balloon go up?
A helium balloon floats because helium gas is lighter than air. By filling a balloon with helium, the balloon also becomes lighter than air. The helium balloon floats for the same reason that objects float on water: objects less dense than water are pushed up by buoyant forces equal to the weight of water displaced by that object. What happens in water also happens in air, and the helium balloon is pushed upwards by a force equal to the weight of air it displaces.
What happen when a balloon is filled with helium?
Helium is lighter than air and a balloon filled with helium may rise up.
Is a helium balloon heavier than air filled balloon?
No. Helium is lighter than air
A basic gas lighter than air?
Hydrogen and Helium are both lighter than air.
Why does a helium balloon float in the air rathen than sink?
because helium is ligter than air
Is helium lighter or heavier?
Helium is lighter than air
Is helium lighter than earth?
yes. helium is lighter than earth or even air.

Why do helium-filled balloons float up in the air?
Helium is lighter than air.
Why will helium filled balloons float in the air?
Because helium is lighter than air.
When balloons are filled with this they are lighter than air.?
Hot air, hydrogen or helium are lighter than cold air.
When balloons are filled with this they are lighter than air?
Hot air, hydrogen or helium are lighter than cold air.
Why does a helium balloom float in air?
Helium is lighter than air. so balloons filled with helium will float in air
