mole is short for molecular. they are basically one in the same. the molecular mass is in amus, the average mass unit, and the mole is a number that converts amus to grams. a mole is the amount of particle in 12 grams of carbon-12, best explained by avagadros number: 6.022*10^23. this is to say molecular mass is the mass of a molecule, and the molar mass is the amount of moles. so there would be 10 moles in 10 grams of Hydrogen. and a molecule of hydrogen, H2, would be 2.014 amu.
vapour density is defined as the ratio of mass of gas occupying a certain volume at a certain P and T to the mass of hydrogen in the same condition.
PV=nRT=(g/M0)*RT
=>gx=PVM0/RT
and gH2=PV*2/RT (M0=2 for hydrogen)
=>gx/gH2=Mx/2 alternate solution:

The formula is:
M = dRT/P where:
- d is the density in g/L
- R is the gas constant; R = 8,314 462 1 J/mol.K
- T is the temperature in kelvins
- P is the pressure in torr
- M is the molar mass in grams
Object that are large move slowly, so as molar mass increases, velocity decreases.
molar conductivity involves concentration of electrolyte also....but electrolytic conductivity doesn't
Multiplication by what is called a conversion factor. A moles x (bbb grams / 1 mole) in which bbb is the molar mass of the substance.
equal to
What is the chemical 'FE'. Do you mean 'Fe'. If so to answer your question . The molar mass of iron (Fe) is 55.845
You must first calculate the molar mass of the substance. To do so, you add up the molar masses of all the elements that make up the compound, multiplied by the number of atoms of that element in one molecule of the substance. For example, AgNO3 has a molar mass of about 169.8 amu. In one molecule of AgNo3, there is one atom of Silver (molar mass 107.8), one atom of Nitrogen (molar mass 14), and three atoms of Oxygen (molar mass 16). Multiply the molar mass of Silver by the number of Silver atoms (1), multiply the molar mass of Nitrogen by the number of Nitrogen atoms (1), multiply the molar mass of Oxygen by the number of Oxygen atoms (3), add the numbers up and you have the molar mass of the substance (169.8). Step 2 is easy. To convert from grams to moles, you divide the number of grams by the molar mass (units for molar mass are grams per mole, so dividing by molar mass cancels the grams). To convert from moles to grams, you multiply by the molar mass.
gases with the higher molar mass
N is avg molar flux of constituent relative to a fixed location in space and J is molar flux of constituent relative to avg molar velocity of all constituents.
When the mesial buccal cusp of the maxillary first molar is distal to the mesial buccal cusp of the mandibular first molar.
The relationship between microM and nM is a factor of 1000. MicroM (or micromolar) is 1 millionth of 1 molar (1 x 106 microM = 1 M), and nM (nanomolar) is 1 billionth of 1 molar (1 x 109 nM = 1 M) See the link below the answer for the relationship between all metric prefixes.
If the gases have the same molar volume, the stoichiometric ratio would be one to one. Molar volume is the volume occupied by one mole of a substance. This indicates that there is a 1:1 molar ratio of each gas.
They are inversely related. This means that as molar mass increases, the rate of evaporation decreases. This is because as molar mass increases, the intermolecular bonds also get stronger, and it is more difficult to break those bonds and for liquid molecules to jump into a gaseous state.
The rate of effusion of two gases in a mixture is inversely proportional to the square roots of their molar masses.
Molar mass is the mass of particles in one mole of a substance. Molar mass is equal to atomic/ molecular/ formula mass in amu. Formula mass is in atomic mass unit while molar mass is in grams .
Gas leaking through a small hole in its container is called effusion. The rate of effusion depends upon molar mass. The smaller the molar mass, the more quickly a gas will effuse out. Given these gases: He, Ar, CO2, helium will effuse out the fastest because its molar mass is only 4 (compared to 40 for argon and 44 for carbon dioxide.)
These are two different compounds.
Well i would say you lose your first molar between 5 and 7 years old.
Root mean square velocity is the measure of the velocity of gas particles that is used for solving problems. It is the square root of the average velocity-squared of the molecules in a gas. The formula for root mean square velocity is sqrt(3RT/Mm) where Mm is the molar mass of the gas in kg / mole, R is the gas constant, and T is the temperature in kelvin.
