Since there are two oxygen molecules, the molar mass would be twice the atomic weight given in the Periodic Table of elements.
O = 16 g/mole
O2 = 32 g/mole
1 mole of 02 gas has 12,044 281 714.1023 atoms.
It's Oxygen but in gas form. Such as N2 is nitrogen gas. But just N is nitrogen.
The balanced chemical equation for the reaction between oxygen and hydrogen is2H2 + 02 -> 2H2OThus 2.2 moles of oxygen reacts with 4.4 moles of hydrogen to form 4.4 moles of steam (water in gaseous state).The mass of H2O obtained is thus 4.4 x 18.0 = 79.2g.
We breathe in the diatomic gas 02, which then goes into combination with receptors on red blood cells.
Oxygen gas has the molecular formula of O2 and nitrogen gas is N2. The Lewis dot structures that represent both diatomic gases are::O=O: :N:::N:

To determine how many atoms are present in 56 liters of oxygen gas at STP you first need to know that there are two atoms in a single molecule. Then, you would work the scientific formula to determine the number of molecules in the oxygen gas.
We breathe in the diatomic gas 02, which then goes into combination with receptors on red blood cells.
Oxygen. Formula: 02 (its diatomic)
the 02 sensor has nothing to do with gas mileage. it sipley is a sensor that reads the oxygen level in your exhaust for emissions.
It is zero. The number 02 is a number. It is a concept and no physical existence and no mass. So the mass percentage is zero.
Since we know that one mole of any gas at STP is equal to 22.4 L we can multiply 135L by the following conversion: 1 mole/22.4L. When you set up the problem it looks like this: (135L)x 1 mole/22.4L =6.03 moles of oxygen gas The liters cancel out and you are left with moles as your units. Remember, if you have liters and want moles, divide by 22.4 liters; if you have moles and you want liters you multiply by 22.4 liters.
