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?
