3 L of a gas weighs 2 g What is the molecular mass?
Doulosnorthland
3 L / 22.414 /mole = 0.1338 moles of the gas
2 g is 0.1338 moles, or 2/0.1338 = 14.948 g/mole is the molecular weight.
( no real gas this light...methane is closest at 16 g/mole)

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?
86.13
What is the molecular formula of a substance that has an empirical formula of C2H5 and a molecular mass of 58 grams per mole?
If C2H5 was the molecular formula its molecular mass would be 29 ( 12 x 2 + 5 x 1) However, 29 x 2 = 58 the actual molecular mass. So we double up the atoms in C2H5 to C4H10 . C4H10 is the molecular formula.
The molecular mass of 2 moles in H2SO4?
2 moles H2SO4 (98.086 grams/1 mole H2SO4)= 196.172 grams of sulfuric acid====================
What is the molecular formula of a compound that has a molecular mass of 54 and the empirical formula C2H3?
C4H6. C2H3 gives a molecular mass of 27, 54/27 gives 2. Therefore the molecular formula is twice the empirical formula.

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 many moles are in 15g of chlorine gas?
The molecular mass of chlorine gas, Cl2, is 2(35.5) = 71.0 Amount of Cl2 = 15/71.0 = 0.211mol
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!

Why is carbon dioxide heavier than nitrogen?
The density of a gas is proportional to its molecular mass. Nitrogen (N2) contains 2 nitrogen atoms each with a mass of about 14 AMU (atomic mass units) for a total molecular mass of about 44. Carbon dioxide (CO2) contains 2 atoms of oxygen, each with a mass of about 16 AMU and 1 carbon atom with a mass of about 12 AMU for a total mass of 44.
What is calcium fluoride molecular mass?
Calcium Fluoride is CaF2. Therefore, its molecular mass = mass(Calcium + 2 x Flourine) = 40 + 2x19 = 78 u.
What is the molecular formula of a substance that has an empirical formula of C2H5 and a molecular mass of 58 grams per mole?

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.
What is the molecular formula of a compound that has a molecular mass of 54 and the empirical formula C2H3?
C4H6. C2H3 gives a molecular mass of 27, 54/27 gives 2. Therefore the molecular formula is twice the empirical formula.
Why does hydrogen gas diffuses faster than other gases?
The rate of diffusion of a gas is inversely related to the molecular weight of that gas. The lighter the gas, the faster it diffuses. Hydrogen is the lightest of all gases having a molecular weight of only 2. Thus it diffuses faster than all others.
