32
39.95 because that is the molar mass of Argon
16 grams or 32 grams, depending on what you're looking at.The mass of one mole of oxygen atoms is about 16 grams, but oxygen gas exists as a molecule (O2) so 1 mole of (O2) is 32 grams.
The mass of 1 mole of an ionic compound is called the molar mass. It is typically expressed in grams per mole.
The molar mass of a molecule that weighs 1 dalton per mole is 1 gram per mole.
This is equal to the molar mass of this substance.
The molar mass of Dalton is approximately 1 gram per mole.
The molar mass of oxygen gas (O2) is 32 g/mol. To find the weight of 0.8834 moles of oxygen gas, you would multiply the molar mass by the number of moles: 32 g/mol x 0.8834 mol = approximately 28.27 grams.
The molar mass of Argon is 39.95g. Therefore 1 mole of Argon is 39.95g
mass of one mole of oxygen atom is 16 grams. atomic weight of any atom is equal to mass of 1 mol of that atom...
32 as oxygen is diatomic
molar mass =207.2 g / mol no. moles = mass/ molar mass moles = 1 1(207.2) = mass mass of 1 mole lead is 207.2g molar mass =207.2 g / mol no. moles = mass/ molar mass moles = 1 1(207.2) = mass mass of 1 mole lead is 207.2g
The phrase "mass of 1 mole of oxygen" is ambiguous because it does not specify whether it is referring to the molar mass (atomic weight) of oxygen, which is approximately 16 g/mol, or the actual weight of 1 mole of oxygen atoms, which would be 16 grams. The context in which the phrase is used would determine the correct interpretation.
