Determine the mass of phosphorus (V) oxide, which is formed by the interaction of 18.6 g of red phosphorus with an excess of berthollet’s salt.
The reaction for obtaining phosphorus oxide:
6P + 5KClO3 = 3P2O5 + 5KCl.
Phosphorus reacted in an amount of 18.6 g: 31 g / mol = 0.6 mol.
P2O5 was formed 2 times less, and its mass is: 0.6 mol: 2 * 142 g / mol = 42.6 g.
