What is the molar mass of hydrogen gas?

The molar mass of hydrogen gas (H2) is 2.0158g. Hydrogen gas is diatomic therefore it's formula is H2. The atomic mass of hydrogen is 1.0079g and multiplying by the two hydrogen atoms is equal to 2.0158g.


What is the mass of 4 moles of hydrogen gas?

Hydrogen gas is H2. 1 moles H2 has a molar mass of 2.0158. Thus, 4 moles H2 gas has a mass of2.0158 g/mole x 4 moles = 8.063 g


How do you convert mass to moles?

In order to convert an element's mass to moles, you must use the molar mass (either 1 mole/ ___g or ___g/ 1 mole). For example, when converting 300g or Hydrogen gas to moles, you must multiply that initial amount by the molar mass of H2. So 300g H2 (1mol/ 2gH2) = 150 mol H2.


Is the molar mass of gas dependant on the type of gas?

Yes as is the molar mass of anything else.


What is 1.00 mole of H2?

it is equal to its molar mass in weight, which is 2grams


Molar mass of nitrogen gas?

The molar mass of Nitrogen gas, N2, is 28 g/mol.


What is the molar mass of amonia gas?

Molar mass of NH3 = 17.03052g/mol


What is true about the molar mass of chlorine gas?

The Molar Mass is 71.0 g


Molar mass of acetone gas?

molar mass of aceton is 58.08 g/mol


What is the molar mass of oxygen in liters?

The molar mass of any gas in liters is 22.4 For example The molar mass of O2 and O are both 22.4 since gas is compressible.


What is the molar mass of bromine gas?

The molar mas of bromine gas (Br2) is 159.8 g/mol.


What is acetone's percent composition by mass?

%C= 62.0% %H2= 10.4% %O2= 27.5% To find these, you divide the molar mass of the specific element in the compound divided by the molar mass of the entire compound.


Would you expect the particles in chlorine gas to diffuse faster slower than the particles in nitrogen gas?

The rate of diffusion of a gas is inversely related to the square root of the molar mass of the gas. Thus, gas with a lower molar mass will diffuse FASTER than a gas with a higher molar mass. Nitrogen (N2; molar mass 28) will diffuse faster than chlorine (Cl2; molar mass 71). For more information about this, see Graham's Law of Effusion.


What is the molar mass of oxygen?

The molar mass of oxygen gas (O2) is 32. If you look on the periodic table of elements the numbers underneath the symbols for the elements are their molar mass in grams


What is the molar mass of nitrogen gas?

Atmospheric nitrogen is diatomic (N2). The molar mass is 2x the molar mass of monatomic N. 2 x 14.01 = 28.02 g/mol = molar mass N2.


Which is heavier hydrogen gas or oxygen gas?

Oxygen is more heavier then Hydrogen, as for gases the density depends only upon the molar mass.So H2 has a molar mass of 2 g/mole and that of oxygen O2 is 32.Thus Hydrogen gas is 16 times lighter than Oxygen gas.


State one way in which molecues of hydregen and molecues of oxygen different?

The molar mas of H2 is 16; the molar mass of O2 is 32.

What are properties of gas mass?

The speed of the molecules in a gas is proportional to the temperature and is inversely proportional to molar mass of the gas.


Properties of mass gas?

The speed of the molecules in a gas is proportional to the temperature and is inversely proportional to molar mass of the gas.


What is the molar mass of gas oxygen?

Oxygen gas is composed of diatomic O2 molecules. From the periodic table, the atomic weight indicates that the molar mass of oxygen atoms is 16.0g/mole. The diatomic molecule O2 has twice the molar mass as oxygen atoms, and its molar mass is 32g/mole.


What is the molar mass of oxygen gas?

Oxygen gas is composed of diatomic O2 molecules. From the Periodic Table, the atomic weight indicates that the molar mass of oxygen atoms is 16.0g/mole. The diatomic molecule O2 has twice the molar mass as oxygen atoms, and its molar mass is 32g/mole.


What is molar volume?

The molar volume at STP(22.4 L/mol) can be used to calculate the molar mass of the gas.


What is the ratio of the rates of diffusion of hydrogen gas to ethane gas C2H6?

According to Graham's Law of Effusion, the rate of diffusion of a gas is inversely related to the square root of the molar mass. Thus, smaller (lighter) gases diffuse faster than larger, heavier gases. Molar mass of H2 = 2 and molar mass of C2H6 = 30. Sqrt 2 = 1.41 and sqrt 30 = 5.48, so the ratio is 5.48/1.41 = 3.88 or H2 will diffuse almost 4x faster (3.88x) than ethane. The ratio of H2/C2H6 would be the inverse, or 1.41/5.48 = 0.257, meaning that the rate of diffusion of ethane is about 26% that of hydrogen.
