What Is The Molecular Weight Of Arsenic Pentachloride?

Arsenic pentachloride (AsCl5) is a compound composed of one arsenic atom and five chlorine atoms. To calculate its molecular weight, we need to add up the atomic weights of each element in the compound.

The atomic weight of arsenic (As) is 74.92 g/mol, and the atomic weight of chlorine (Cl) is 35.45 g/mol.

So, the molecular weight of AsCl5 can be calculated as follows:

(1 x atomic weight of As) + (5 x atomic weight of Cl)

= (1 x 74.92 g/mol) + (5 x 35.45 g/mol)

= 74.92 g/mol + 177.25 g/mol

= 252.17 g/mol

Therefore, the molecular weight of arsenic pentachloride is 252.17 g/mol.
