The molar mass of phosphorus tribromide (PBr3) can be calculated by adding the atomic masses of its constituent elements: phosphorus (P) has an Atomic Mass of approximately 31.00 g/mol, and bromine (Br) has an atomic mass of about 79.90 g/mol. Since there are three bromine atoms in PBr3, the total mass is 31.00 g/mol + (3 × 79.90 g/mol) = 31.00 g/mol + 239.70 g/mol = 270.70 g/mol. Therefore, the molar mass of PBr3 is approximately 270.70 g/mol.

How many grams of bromine atoms are present in a 12.9 mole sample of pbr3?
In a sample of phosphorus tribromide (PBr3), each molecule contains three bromine (Br) atoms. Therefore, in 12.9 moles of PBr3, there are ( 12.9 , \text{moles} \times 3 , \text{moles of Br per mole of PBr3} = 38.7 , \text{moles of Br} ). To find the mass of bromine, multiply the number of moles of Br by its molar mass (approximately 79.9 g/mol): ( 38.7 , \text{moles} \times 79.9 , \text{g/g} \approx 3084.63 , \text{grams} ). Thus, there are approximately 3084.63 grams of bromine in the sample.
What is the interactive force between PBr3?
The atoms in a molecule of phosphorus tribromide, PBr3, are held together by polar covalent bonds.
Is pbr3 dipole dipole?
Phosphorus tribromide (PBr3) is a polar molecule due to the difference in electronegativity between phosphorus and bromine, resulting in a dipole moment. However, the primary intermolecular forces in PBr3 are dipole-dipole interactions because of this polarity. Additionally, PBr3 may exhibit some London dispersion forces, but dipole-dipole interactions dominate in this case.
What properties stay the same during physical and chemical change?

What is the ratio of mass a to mass b?
To determine the ratio of mass a to mass b, you simply divide mass a by mass b. This can be expressed as a:b, which is equal to a/mass b. If you have the specific values for mass a and mass b, you can calculate the numerical ratio accordingly.

The atoms in a molecule of phosphorus tribromide, PBr3, are held together by polar covalent bonds.
What is the oxidation number of PBr3?
The oxidation number of phosphorus (P) in PBr3 is +3. This is because bromine (Br) has an oxidation number of -1 and since there are 3 bromine atoms in PBr3, the overall charge must balance out to zero.
Is pbr3 dipole dipole?
Phosphorus tribromide (PBr3) is a polar molecule due to the difference in electronegativity between phosphorus and bromine, resulting in a dipole moment.
