What is r500 refrigerant?
What is r500 refrigerant?
Summary. R-500 is a colorless and odorless CFC refrigerant that was completely banned from production by 1996 under the Montreal Protocol for depleting the ozone. R-500 is used in commercial air conditioning and in some dehumidifier applications. It Is high-pressured and typically stored in yellow containers.
How many molecules are in a gram?
The definition of Avogadro’s number of 6.022 × 1023/mole is the number of atoms or molecules per one gram atomic weight. For one gram atomic weight of hydrogen with atomic weight of one gram, one mole of hydrogen contains 6.022 × 1023 hydrogen atoms.
What is the formula of refrigerant?
ASHRAE Refrigerant Designations
| Number | Chemical Name | Chemical Formula |
|---|---|---|
| 124 | 2-chloro-1,1,1,2-tetrafluoroethane | CHClFCF 3 |
| 125 | pentafluoroethane | CHF 2CF 3 |

How many grams is a water molecule?
18 g/
Water consists of one oxygen atom and two hydrogen atoms. This means that the mass of a water molecule is 1g + 1g + 16g = 18 g/ mol.
What is R 502 used for?
R502 Refrigerant Developed for use in low temperature refrigeration (the evaporator pressure stays out of vacuum down to -40°F). R-502 offers lower discharge temperature and improved capacity compared to R-22.
What is the replacement for R11?
Replacements for R11 R-11 is now being replaced by other environment friendly refrigerants, of which the most common is R-123. If the R-11 refrigeration equipment that were manufactured before 1990 are being replaced by R-123 (dichlorotrifluoroethane) refrigerant then some alteration would be required in the chiller.
What is the mass of 1 gram molecule of oxygen?
The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu. ⇒ 5.31 × 10-23g….Thank you.

How are chemical refrigerants assigned a Your Number?
Chemical refrigerants are assigned an R number which is determined systematically according to molecular structure.
How do you convert from molecules to grams?
Avogadro’s number is given as 6.022 x 10^23. Avogadro’s number is a constant that represent the number of molecules or atoms per mole of any given substance. To work out a calculation, student must also know that the molar mass of the substance, which can be found from its chemical formula and is given in grams per mole.
How to calculate the molecular mass of freon-11?
Calculate the molecular mass of trichlorofluoromethane, also known as Freon-11, whose condensed structural formula is CCl 3 F. Until recently, it was used as a refrigerant. The structure of a molecule of Freon-11 is as follows: Unlike molecules, which form covalent bonds, ionic compounds do not have a readily identifiable molecular unit.
How to calculate the mass of a substance in grams?
The calculator below calculates the mass of the substance in grams or the quantity of the substance in moles, depending on the user’s input. It also displays the molar mass of the chemical compound and details of its calculation just for reference.
