The molecular mass of the compound is 137.32 g/mol. what is the molecular formula of the compound? pcl2 pcl3

The molecular formula of the compound is

Explanation:

Molecular mass of the compound is defined as the sum of the masses of all the individual atoms present in a compound.

We are given a molecular mass of 137.32 g/mol and we need to find the molecular formula for this molecular mass. For that we calculate the molecular mass of the given compounds individually and then match the given molecular mass.

Molar mass of phosphorous = 30.974 g/mol

Molar mass of chlorine = 35.453 g/mol

As, the molecular mass of   matches the given molecular mass.

Hence, the molecular formula of the compound is

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
