Is O2 mass 16 or 32?
O2 is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu.
How much is a mole of oxygen gas?
The approximate mass of one mole of oxygen gas is 32 grams per mole.
Which of the following is correct for 1 mole methane?
One mole of methane specifies NA , Avogadro’s number of methane molecules, i.e. 6.022×1023 individual CH4 molecules. And thus it contains 4×6.022×1023 hydrogen atoms .
Is the mass of 1 mole of O and 1 mole of S same?
O molecules contains 6.022 x 1023 molecules. 1 mole contains 6.022 x 1023 entities (Avogadro’s number) Concept 1. … One atom of sulfur has a mass of 32.07 amu; one mole of S atoms has a mass of 32.07 g.
What is the mass of 1 ion of oxygen?
An ion refers to the electrically charged atoms after losing or gaining electrons. Mass refers to the measure of number of atoms in an element or a compound. Now, since 1 mole of oxygen atoms = 16 units and every mole of oxygen contains 6.023 × 1023 atoms, Hence, 1 oxygen ion weighs = 1/6.023 × 1023 u.
