What is hydrogen's atomic mass number?
Hydrogen is a gas. Mass number of it is 2.
What is the oxidation number of hydrogen usually?
Hydrogen gas (H2) Oxidation number is 0. Hydrogen (H+) is +1.
How many moles of hydrogen gas are in 5.04 grams in hydrogen gas?
To find the number of moles of hydrogen gas, we first need to convert the mass of hydrogen gas from grams to moles using the molar mass of hydrogen gas (2 g/mol). 5.04 grams of hydrogen gas is equal to 5.04 g / 2 g/mol = 2.52 moles of hydrogen gas.

Hydrogen gas H2 is a promising alternative to fossil fuels How many molecules are present in 1.0 kg of hydrogen gas?
To determine the number of molecules in 1.0 kg of hydrogen gas, we need to convert the mass to moles using the molar mass of hydrogen. The molar mass of hydrogen (H2) is 2.02 g/mol. Then we can use Avogadro's number (6.022 x 10^23) to find the number of molecules in one mole of hydrogen gas.
What is heavier Hydrogen gas or oxygen gas How do you know?
Oxygen is heavier as it has a mass number of 16 whereas hydrogen has a mass number of 1. Both form diatomic molecules (molecules of two atoms) making the formula masses 32 for oxygen and 2 for hydrogen.
Is hydrogen a gas?

Is hydrogen gas a element?
No. Although hydrogen is an atom, it doesn't exist by itself (except as an ion). Hydrogen gas is a hydrogen molecule made of two hydrogen atoms.
