Detailed explanation-1: -The mass of 2.50 mole of oxygen gas ( ) is 80 g.
Detailed explanation-2: -There are two moles oxygen. So, the answer is 63. 9976 g. Was this answer helpful?
Detailed explanation-3: -1)2.5 moles of Cl2 contains (2.5 * Avogadro no.) Number Of molecules. Now that is equal to 2.5 moles of oxygen, which weighs 32*2.5 grams = 80 grams Hence the mass of oxygen o2 is 80 grams.
Detailed explanation-4: -AI Recommended Answer: There are 8.30x104-24 atoms of oxygen in 2.50 mol of oxygen gas. There are 7.53x10*23 atoms of oxygen in 2.50 mol of oxygen gas.
Detailed explanation-5: -The mass of 2.5 moles of electrons is 2.277 × 10-30 kilograms, which is calculated by multiplying 9.109 × 10-31 kilograms by 2.5. The mass of 1 mole of electrons is 9.109 × 10-31 kilograms. Therefore, the mass of 2.5 moles of electrons is 2.277 × 10-30 kilograms.
