Consider the following balanced equation:

algol [13]

Moles of PF₃ : 4

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

$\tt P_4(s)+6F_2(g)\rightarrow 4PF_3(g)$

1.25 moles of P₄(s) is reacted with 6 moles of F₂(g)

Limiting reactant : the smallest ratio (mol divide by coefficient)

P₄ : F₂ =

$\tt \dfrac{1.25}{1}\div \dfrac{6}{6}=1.25\div 1\rightarrow F_2~limiting~reactant(smallest~ratio)$

mol PF₃ based on mol of limiting reactant(F₂), so mol PF₃ :

$\tt \dfrac{4}{6}\times 6~moles=4~moles$
