Molecular mass equals 2vapour density?
vapor density =density of gas/density of hydrogen gas=mass of a certain vol. of gas/mass of same vol. of hydrogen gas=mass of n molecules of gas/mass of n molecules of hydrogen gas=mass of 1 molecule of gas/mass of 1 molecule of hydrogen gas=molecular mass of gas/molecular mass of hydrogen gas=molecular mass/22 x vapor density=molecular mass
Which gas has the lowest mass per mole?
Hydrogen gas has the lowest mass per mole, with a molar mass of approximately 2 grams per mole.
Which is more heavier - hydrogen gas or oxygen gas?
Mass of Hydrogen gas:- 2g/mol Mass of Oxygen gas :- 32g/mol Therefore, Oxygen gas is more heavier
In a laboratory 178.8g of water is separated into hydrogen gas and oxygen gas . The hydrogen gas has a mass of 20.0g. What is the mass of the oxygen gas produced?
It would be 10.8 + 77.3.So that would be 88.1g of water in the scale you are using.
How much hydrogen gas is produced when steam is passed over hot iron?
When steam is passed over hot iron, the reaction produces iron oxide and hydrogen gas. The amount of hydrogen gas produced depends on the reaction conditions such as temperature, pressure, and quantity of iron. From the balanced chemical equation, for every mole of iron that reacts, one mole of hydrogen gas is produced.
What is the relative mass formula of hydrogen gas?
The molecular mass of hydrogen gas is 2. A molecule of hydrogen gas contains two hydrogen atoms covalently bonded. Since each hydrogen atom has an atomic mass of 1 (as we can derive from the Periodic Table of Elements), the molecular mass of hydrogen gas as a molecule is 1 + 1 = 2.
Molecular mass equals 2vapour density?
vapor density =density of gas/density of hydrogen gas=mass of a certain vol. of gas/mass of same vol. of hydrogen gas=mass of n molecules of gas/mass of n molecules of hydrogen gas=mass of 1 molecule of gas/mass of 1 molecule of hydrogen gas=molecular mass of gas/molecular mass of hydrogen gas=molecular mass/22 x vapor density=molecular mass
What is hydrogen's atomic mass number?
Hydrogen is a gas. Mass number of it is 2.
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.
Which gas has the lowest mass per mole?
Hydrogen gas has the lowest mass per mole, with a molar mass of approximately 2 grams per mole.
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.
How many moles are in 18.0grams of hydrogen gas?
To find the number of moles in 18.0 grams of hydrogen gas, you need to divide the given mass by the molar mass of hydrogen gas. The molar mass of hydrogen gas (H2) is about 2.016 grams/mol. So, 18.0 grams / 2.016 grams/mol ≈ 8.93 moles of hydrogen gas.
What would happen if you hold a burning stick under hydrogen gas?
If anything burning is inserted into, or placed around a mass of Hydrogen gas, it will ignite the Hydrogen, causing it to "explode". The resulting explosion is very hot, and if done with too much Hydrogen gas, can be dangerous. Exercise caution when preforming this.
Mass of Hydrogen gas molecule?
The mass of a hydrogen gas molecule (H2) is approximately 2 atomic mass units (amu). This is because each hydrogen atom has a mass of roughly 1 amu, and a hydrogen gas molecule consists of two hydrogen atoms bonded together.
Which is more heavier - hydrogen gas or oxygen gas?
Mass of Hydrogen gas:- 2g/mol Mass of Oxygen gas :- 32g/mol Therefore, Oxygen gas is more heavier
In a laboratory 178.8g of water is separated into hydrogen gas and oxygen gas . The hydrogen gas has a mass of 20.0g. What is the mass of the oxygen gas produced?
It would be 10.8 + 77.3.So that would be 88.1g of water in the scale you are using.
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.
