What is the mass of 34.6 L of oxygen? How many molecules of oxygen are in 34.6 L of oxygen?

49.4 grams; 9.29 x 10^23 molecules O2

Explanation:

In order to solve for the mass of oxygen, you first must find out how many moles of oxygen there are in 34.6 L.

There are 22.4 L in one mole of gas, so to get amount of moles, divide 34.6 by 22.4.

34.6 / 22.4 = 1.544 mol

In order to calculate mass, multiply the amount of moles by the molar mass of oxygen, which is in this case 32.00 g/mol.

1.544 * 32.00 = 49.4 grams

To calculate the amount of molecules, multiply the amount of moles by Avogadro's number, 6.02 x 10^23, which basically represents how many atoms/molecules there are in a mole of any substance.

1.544 * (6.02 x 10^23) = 9.29 x 10^23 molecules O2

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
