WebOne mole of oxygen atoms contain s 6.02214179 × 1023 oxygen atoms. Also, one mole of nitrogen atoms contain s 6.02214179 × 1023 nitrogen atoms. The numb er 6.02214179 × … Web19 jan. 2024 · Explanation: First, we need to calculate the molar mass of oxygen gas. Oxygen gas is O2. O2 has a molar mass of 32g/mol. ∴ MolesO2 = 40g 32g/mol. ∴ MolesO2 = 40g 32g/mol. MolesO2 = 1.25mol. ∴ There are 1.25 moles of … can als show up on mri
Is Oxygen O2 or O: The Molecular Structure of This Element
Web27 feb. 2016 · Explanation: STP is irrelevant - it's a detractor. Mass is not dependent on temperature or pressure. The number of molecules of O2 are dependent only on the moles of O2 in 10.0 g O2. Determine the molar mass of O2, which is (2 ×15.998g/mol) = 39.998 g/mol. 1mol of molecules = 6.022 × 1023molecules. You will make the following … Web30 dec. 2024 · As oxygen belongs to the 16th group in the periodic table and fluorine is in the 17th group. ⇒ Oxygen valence electrons = 6 ⇒ Fluorine valence electrons = 7 ∴ Total valence electrons available for drawing the OF2 lewis structure = 6 + 7 (2) = 20 valence electrons [∴ OF2 molecule contains one oxygen and two fluorine] 2. WebThe oxygen molecule (O2) has 16 electrons. In ground state (the most stable state of oxygen), the last two electrons of the oxygen molecule are located in a different π* antibonding orbital. These two unpaired electrons have the same quantum spin number (they have parallel spins) and qualify ground state oxygen to be a di radical. canal staffordshire
