Does oxygen have a greater mass than chlorine?

Atomic oxygen does not have a greater atomic mass than chlorine, nor does molecular oxygen. The atomic mass of chlorine is approximately 35 g/mol, while molecular (O2) oxygen has a molecular mass of 32 g/mol.


Which gas effuses faster at the same temperature molecular oxygen or atomic argon?

Molecular oxygen will effuse faster because: Molar Mass of O2: 32g Atomic Mass of Ar: 40g


How many grams of O2 are in 5.0 mole of the element?

O2 has a molecular mass of 31.9988 grams per mol. Therefore, 4.5 moles of O2 will equal 144 grams of oxygen.


Can density be seen?

Density is not a visual quality. But we can infer information about density by observing. For example moist air is lighter than dry air - that is why the clouds condense at higher altitudes, not at ground level. {Explanation - H2O has an molecular mass of 28; O2 has an molecular mass of 32; N2 has an molecular mass of 34. Hence H2O vapour is lighter than O2 or N2.}


How many grams are there in 2.047 moles of O2?

For this you need the atomic (molecular) mass of O2. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.2.047 moles O2 × (32.0 grams) = 65.5 grams O2


What are the masses of molecular oxygen O2 hydrogen H2 and nitrogen in grams?

The mass of O2 is approximately 32.00g/mol. The mass of H2 is about 2.016g/mol. These masses can be obtained by using the atomic weights of the atoms that make up these molecules.

Where does air get its mass?

Air gets it's mass from the molecules molecular weight. Common gases in air are nitrogen, oxygen, carbon dixoide, and others. If you consider the Atomic weight/mass of each element or molecule when they combine with others you get mass. For example Oxygen in there cannot exist alone as O because it is a Diatmoic element so there is always O2. The molecular weight of O2 is 32 grams/mole. Hope that helps.

What is the formula for ozone?

The formula weight for O3 is the same as the molecular weight which is taking all the elements, multiplying its mass, and then adding the products. Oxygen's mass is 16 g on the periodic table & there's three of them so: 16x3= 48 g (molecular weight) = This is your Formula weight. Hope that helped.
