Hint:This question gives the knowledge about the molecular formula and weight of the chemical compounds. The molecular formula is the way of representing the chemical compounds. The molar mass is the sum of masses of the individual elements.
Complete answer:
The molar mass is the sum of masses of the individual elements.
The molar mass of phosphorus, is determined by summing up all the atoms of phosphorus present in this molecule. The molecular weight of one phosphorus is . So, the molecular weight of phosphorus molecules is .
Therefore, the molar mass of phosphorus, is .
Additional information: Allotropy is defined as the property by which chemical substances can be expressed in two or more differentiable forms having the same physical states. The allotropes of a substance differ only on the basis of bonding. The important example of allotrope is phosphorus. The allotropes of phosphorus are red phosphorus, black phosphorus and white phosphorus.
Pressure, light and temperature leads to changes in allotropic forms. Allotropes differ on the basis of their physical and chemical properties. Allotropy generally occurs in chemical species or chemical elements. They may exist in simpler or very complicated forms.
The allotropes of phosphorus are red phosphorus and white phosphorus. The reactions possesses by them are as follows:
The process of burning of white phosphorus in the presence of sufficient amounts of oxygen leads to the formation of phosphorus pentoxide. The reaction for process of preparation of phosphorus pentoxide is as follows:
The process of burning phosphorus in the presence of sufficient amounts of oxygen leads to the formation of phosphorus trioxide at very low temperature. The reaction for process of preparation of phosphorus trioxide is as follows:
Note:
You should have complete knowledge about the molecular formula is the way of representing the chemical compounds. It comprises the chemical symbols for the elements tailed by the numeric subscripts labelling the atoms of each element present in a molecule.
