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 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
What is the Molecular mass of 2-pentanone?
The molecular mass of 2-pentanone (C5H10O) is 86.13 g/mol.
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
What is the molecular mass of Cl 2?
The atomic mass of chlorine is 35.5. A chlorine molecule has two chlorine atoms. Therefore its molecular mass is 71u.

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.
What is the Molecular mass of 2-pentanone?
The molecular mass of 2-pentanone (C5H10O) is 86.13 g/mol.
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!
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
What is the molecular mass of Cl 2?
The atomic mass of chlorine is 35.5. A chlorine molecule has two chlorine atoms. Therefore its molecular mass is 71u.
What is the molecular formula of a substance that has an empirical formula of C2H5 and a molecular mass of 58 grams per mole?
The empirical formula of C2H5 corresponds to an empirical mass of 29 g/mol. To find the molecular formula from the empirical formula and molecular mass, divide the molecular mass by the empirical mass to get the "scaling factor" (58 g/mol ÷ 29 g/mol = 2). Multiply the subscripts in the empirical formula by the scaling factor to get the molecular formula: C2H5 x 2 = C4H10. So, the molecular formula is C4H10.
What is calcium fluoride molecular mass?
Calcium Fluoride is CaF2. Therefore, its molecular mass = mass(Calcium + 2 x Flourine) = 40 + 2x19 = 78 u.
The molecular mass of 2 moles in H2SO4?
2 moles H2SO4 (98.086 grams/1 mole H2SO4)= 196.172 grams of sulfuric acid====================
Atomic mass of cholrine is 355 and its molecular mass 71 the atomicity is what?
The atomic mass of chlorine is not 355 it is 35.5 (approx). So, if the molecular mass is 71 then the atomicity is 71/35.5 = 2.
How many moles are in 15g of chlorine gas?
To calculate the number of moles in 15g of chlorine gas, you need to use its molar mass. The molar mass of chlorine is approximately 35.5 g/mol. Divide the given mass by the molar mass to find the number of moles. For 15g of chlorine gas, you will have about 0.42 moles.
