Elemental Phosphorus (P₄) Reacts Vigorously with Halogens at Room Temperature $\rightarrow$

Short Answer

Elemental phosphorus (P₄) reacts vigorously with halogens at room temperature to produce phosphorus trihalides.How many grams of PF₃ (87.97 g/mol) can be produced using excess fluorine (38.00 g/mol) and 5.49 g P₄ (123.88 g/mol)?
P ₄ (s) + 6 F₂ (g) $\rightarrow$ 4 PF₃ (g)
