What was the concentration of tetrafluoromethane in air samples in 1980?

Air samples collected at altitudes of 10 to 33 km at 44 deg N (southern France) in 1980 contained tetrafluoromethane; its mixing ratio was measured as 65 parts per trillion by volume at 14.4 km and 62 parts per trillion by volume at 33.2 km (1). Median tetrafluoromethane concentrations from remote, suburban, and source dominated sites were 0.070, 0.095, and 0.140 ppb by volume, respectively, for the years 1980 to 1987 (2).

In contrast to CFCs, hydrofluorocarbons have no adverse effect on the ozone layer and only a low contribution to global warming ... The latter effect could be further minimized by avoiding leakages in refrigeration and air-conditioning equipment and by refrigerant recycling. /Hydrofluorocarbons/

What is the molar mass of an element?

The molar mass of elements in grams per mole is numerically equal to their atomic mass in unified atomic mass units (u) or daltons (Da). The molar mass of compounds is equal to the sum of molar masses of the atoms which form the compound. For example, the molar mass of water (H₂O) is approximately 1 × 2 + 16 = 18 g/mol.

How to find the molar mass of a compound?

Finding the molar mass by means of calculating the sum of the atomic weight of the atoms, which form the compound multiplied by their numbers.

How to calculate molecular mass?

Molecular mass (older name molecular weight) is the mass of a molecule calculated as the sum of the mass of each atom in the molecule multiplied by the number of atoms of that element in the molecule. Molecular mass is a dimensionless quantity numerically equal to the molar mass. Though molecular and atomic mass values are dimensionless, they are given the unit dalton (Da) or unified atomic mass unit (u), which is approximately the mass of a single proton or neutron and is numerically equivalent to 1 g/mol.

What is the unit of mass?

The molar mass is a physical property, which is defined as the mass of a substance divided by its amount of substance in moles. In other words, it is the mass of one mole of a particular substance. In SI, the unit for molar mass is kg/mol. However, chemists almost always express molar masses in g/mol for convenience.

What is the mole of a substance?

All substances consist of atoms or molecules. In chemistry, it is important to measure their amounts accurately. The mole is used to express the amounts of reactants and products of chemical reactions. The mole, symbol mol, is the SI unit of the amount of substance. One mole contains exactly 6.02214076×10²³ elementary entities. This number is the fixed numerical value of the Avogadro constant, N A, when expressed in the unit mol⁻¹ and is called the Avogadro number. The amount of substance, symbol n, of a system is a measure of the number of specified elementary entities. An elementary entity may be an atom, a molecule, an ion, an electron, any other particle or specified group of particles.
