The number of moles of required to produce 250 grams of would be 3 moles.
<h3>Stoichiometric problem</h3>
Phosphorus and chlorine react to form phosphorus pentachloride according to the following balanced equation:
From the equation of the reaction, the mole ratio of chlorine and phosphorus pentachloride is 5:2. Thus, 5 moles of chlorine will produce 2 moles of phosphorus pentachloride.
Recall that: mole = mass/molar mass
The molar mass of is 208.24 g/mol
Thus, 250 g of would be equivalent to:
mole = 250/208.24
= 1.20 mol
2 mol = 5 moles
1.20 mol = 5 x 1.2/2
= 3 moles
In other words, 250 g will require 3 moles of .
