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 the gram molecular mass of hydrogen?
The gram molecular mass of H2 is 2g.
What is the molecular mass of hydrogen?
For H2 (natural occurring element Hydrogen) it is 2*1.00794 a.m.u = 2.01588 a.m.eThis means that 1.00000 mole H2 has a mass of 2.01588 grams
How do you calculate the atomic mass of bromine?
To calculate the atomic mass of any element, add the no. of protons and neutrons. There sum will be the atomic mass. The mass of electrons is not counted towards the atomic mass.
The molecular mass of a compound is 63.008 amu contains Hydrogen and Oxygen and Nitrogen elements It molecular formula is?
HNO3
Which gas effuses the fastest bromine or chlorine or ammonia or Hydrogen?
due to least molecular mass H2 gas effuses most rapidly.

What is the method of working out the molecular mass of hydrogen?
On the periodic table it says that one mole of hydrogen atoms weighs 1.008 grams. However, Hydrogen is a diatomic molecule (it is composed of two hydrogen atoms in its molecular state). Hence, the molecular mass of hydrogen is 1.008 multiplied by 2 = 2.016g this is the mass of one mole of hydrogen. Hope this helps!
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.
How do you calculate the atomic mass of bromine?
To calculate the atomic mass of any element, add the no. of protons and neutrons. There sum will be the atomic mass. The mass of electrons is not counted towards the atomic mass.
What formula is used to calculate the atomicity of elements?
atomic mass/molecular mass
What element forms a diatomic gas with a mass of 160 amu?
Bromine (Br) has a molar mass of 79.904 amu (atomic mass units), which is extremely close to 80. Bromine is diatomic so when two bromine molecules are put together to create a diatomic gas, the molar masses of each bromine add to get a combined molar mass of 160 amu.
Why does nitrogen have a lower boiling point than bromine?
nitrogen has lower mass and weaker molecular forces of attraction
How do you calculate Mr?
To calculate the relative molecular mass (Mr) of a molecule, add up the atomic masses of all the atoms in the molecule as shown in its molecular formula. For example, the Mr of H2O (water) is calculated by adding the atomic masses of 2 hydrogen atoms and 1 oxygen atom.
How do you calculate the mass number of isotopes for Hydrogen?
Hydrogen is a non metal element. Mass number of it is 1.
