39.95 because that is the molar mass of Argon
32 as oxygen is diatomic
The molar mass of diatomic nitrogen (N2) is approximately 28.02 g/mol. Therefore, the mass of one mole of diatomic nitrogen gas is 28.02 grams.
Mass and the number of mole in a given sample are related quickly with the equation #MOLE = MASS/MOLAR MASS Where the mass is in grams. Now, we know that the number of mole is one, and the molar mass can be found with any periodic table - 1.00794 abouts. Now, the equation reads 1 = MASS/1.00794 This can be rearranged through simple mathematics into 1*1.00794 = MASS/1.00794 * 1.00794 Or 1*1.00794 = MASS Since anything multiplied by one is itself, this can be simplified to 1.00794 = MASS So, the mass of 1 mole of Hydrogen is 1.00794 grams. Also, your question was a sentence :p
The molar mass of Argon is 39.95g. Therefore 1 mole of Argon is 39.95g
The mass of 1 mole of an ionic compound is called the molar mass. It is typically expressed in grams per mole.
Chlorine is non metal element. Atomic mass of it is 35.
Hydrogen gas has the lowest mass per mole, with a molar mass of approximately 2 grams per mole.
32 as oxygen is diatomic
The molar mass of diatomic nitrogen (N2) is approximately 28.02 g/mol. Therefore, the mass of one mole of diatomic nitrogen gas is 28.02 grams.
One mole of O₂ gas occupies approximately 22.4 liters at standard temperature and pressure (STP), which is 0 degrees Celsius and 1 atmosphere of pressure. The molar mass of O₂ is about 32 grams, meaning that 1 mole of O₂ weighs 32 grams. Thus, under STP conditions, 1 mole of O₂ gas will have both a specific volume and mass.
It weights the same as one times the molar mass in g/mol. It is NOT important to be ideal, it even needn't to be necessarily a gas, only the kind of compound is important.
1 standard volume of 1 mole of any gas @ STP is 22.4 LSo the # of moles in a 1 L sample will be:1 L*(1 mol/22.4 L) = 0.04464 molSince you already know the mass of the gas @ STP, the molar mass will be mass/#moles1.92 g/ 0.04464 mol = 43.01 g/mol
Mass and the number of mole in a given sample are related quickly with the equation #MOLE = MASS/MOLAR MASS Where the mass is in grams. Now, we know that the number of mole is one, and the molar mass can be found with any periodic table - 1.00794 abouts. Now, the equation reads 1 = MASS/1.00794 This can be rearranged through simple mathematics into 1*1.00794 = MASS/1.00794 * 1.00794 Or 1*1.00794 = MASS Since anything multiplied by one is itself, this can be simplified to 1.00794 = MASS So, the mass of 1 mole of Hydrogen is 1.00794 grams.

The molar mass of Argon is 39.95g. Therefore 1 mole of Argon is 39.95g
for Apex: can be found easily from the periodic table is the mass of a mole of the gas
The mass of 1 mole of an ionic compound is called the molar mass. It is typically expressed in grams per mole.
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will be the atomic mass. Helium's atomic mass is 4.003 grams.
