The molecular weight of oxygen is 16. Its atomic symbol is O and atomic number is 8. It is a gas in its natural state.
O2 has a molecular mass of 31.9988 grams per mol. Therefore, 4.5 moles of O2 will equal 144 grams of oxygen.
The bond in the molecule O2 is covalent.
The molecular mass of cytosine is approximately 111.1 grams per mole.
The molecular mass of water vapour is 18.01528
The gram molecular mass of hydrogen is 1 gram per mole.
O2 has a molecular mass of 31.9988 grams per mol. Therefore, 4.5 moles of O2 will equal 144 grams of oxygen.
The molecular weight of O2 (oxygen gas) is approximately 32 g/mol.
It stands for molar mass. You simply add the mass numbers of each element to get a total. So, for O2, the answer would be 16+16 (because there are two oxygens) and the total is 32.
The molecular formula for oxygen is O2, indicating that it consists of two oxygen atoms bonded together.
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.
The molar mass of O2 is 32 g/mol, H2 is 2 g/mol, and N2 is 28 g/mol. To calculate the mass in grams, you would multiply the molar mass by the number of moles of the substance. For example, for 1 mole of O2, the mass would be 32 grams.
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.

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
The bond in the molecule O2 is covalent.
The relationship between molecular geometry and O2 bond angles is that the molecular geometry of O2 is linear, meaning that the bond angle between the two oxygen atoms is 180 degrees.
The formula of an oxygen molecule is O2 (2 is a subscript but now WA doesn't permit to write a subscript).15.9994 g/mol is the molecular mass of oxygen. Formula mass is a sum of atomic mass of atoms in the molecule. In O2 there are two oxygen so it will be about 32g/mol
