Molecular oxygen
O2
O2 is a molecule made up of two oxygen atoms. Oxygen itself is an element, but when it combines with another oxygen atom to form O2, it is considered a molecule.
Oxygen (O2)
O2 is not a compound , it is the element oxygen.
co2 and o2
Oxygen is an element and does not have a monomer. It exists as O2 molecules in its diatomic form in nature.
H2O+O2 (water and oxygen)
co2 and o2
Oxygen (O) is an element, while O2 is a molecule composed of two oxygen atoms bonded together. So, O2 is a molecule, not a compound.
Oxygen is an element. And it is found as a gas in the atmosphere as a diatomic molecule of two oxygens (O2).
to convert an element to moles you need to setup and equation, for our example we will be using 5g of O2 or oxygen. You need to know what O2's molar mass is as well, it is 32g. So the equation would be 5g of O2 / 32 = .16 moles of O2. So to convert moles to grams all you do is multiply the moles given by the molar mass of the element/compound and you have your grams Hoped this helped : )
