The last 'molecules' should be taken off, it messes up the question, you already have your unit.

How many hydrogen atoms are in 45.0 grams of hydrogen gas?
45,0 grams of hydrogen gas have 135,5.10e23 atoms.
How many grams of hydrogen are there in thirty grams of methane gas?
8 grams. Or more exactly, in 30.0 grams of methane there is 7.54 grams of hydrogen.
How many molecules of PF3 are in a gas cylinder containing 150.0 grams of PF3?
1.433 × 1026
Why atomic hydrogen is more reactive than hydrogen gas?
Hydrogen gas at standard temperature and pressure exists as diatomic molecules, and much of the chemical potential energy of atomic hydrogen has been evolved as heat along with forming the diatomic molecules.
What is produced when the covalent bond in water molecules is broken?
When the covalent bond in water molecules is broken, it produces hydrogen gas (H2) and oxygen gas (O2) as the products.
How many hydrogen atoms are in 45.0 grams of hydrogen gas?
45,0 grams of hydrogen gas have 135,5.10e23 atoms.
How many moles of hydrogen gas are in 5.04 grams in hydrogen gas?
5 moles
How many grams of hydrogen are there in thirty grams of methane gas?
8 grams. Or more exactly, in 30.0 grams of methane there is 7.54 grams of hydrogen.
What do hydrogen and hydrogen make?
Hydrogen gas molecules
How many grams of oxygen are there in 17800 grams hydrogen sulfate?
It is not measured in grams but PPM because it is a gas.
Does hydrogen gas have a hydrogen to carbon ratio of infinity?
No. Hydrogen gas is Hydrogen molecules floating around. They are looking for Oxygen molecules with which to make water.
How many molecules in 38 grams of oxygen gas?
38 grams oxygen gas (1 mole O2/32 grams)(6.022 X 1023/1 mole O2) = 7.2 X 1023 molecules of oxygen gas -------------------------------------------------
Hydrogen gas H2 is a promising alternative to fossil fuels How many molecules are present in 1.0 kg of hydrogen gas?
Aprox. 3.1023
Do hydrogen molecules or hydrogen gas conduct electricity?
Neither
How many grams of water could be made from 5.0 mol H2 and 3.0 mol O2?
The formula for Oxygen gas is O2, and the formula for water is H2O. Each molecule of Oxygen gas can produce 2 molecules of water (with enough Hydrogen, of course). So, 2.5 moles of Oxygen gas would be required to produce 5.0 moles of water.
Is hydrogen made of gas?
Hydrogen molecules, which is hydrogen atoms linked together.
What is hydrogen gas made of?
Hydrogen molecules, which is hydrogen atoms linked together.
