What is the formula of atomic mass?
Calculating Average Atomic Mass
Average atomic mass = f1M1 + f2M2 +… + fnMn where f is the fraction representing the natural abundance of the isotope and M is the mass number (weight) of the isotope. The average atomic mass of an element can be found on the periodic table, typically under the elemental symbol.
What are 5 uses of chlorine?
Chlorine also has a multitude of industrial uses. Including making bulk materials like bleached paper products, plastics such as PVC and the solvents tetrachloromethane, chloroform and dichloromethane. It is also used to make dyes, textiles, medicines, antiseptics, insecticides and paints.

What is the formula of chlorine gas?
What is the mass of 2.5 moles of chlorine gas at STP?
Answer: Cl2 contains two Cl atom so molar mass will be 35 . 5 x2 that is 71 GRAM means 0ne mole of Cl2 has 71 gram so 2.5 mol will be equal to 2.5×71.
