Write the equation for the reaction of phosphorus combustion. Determine the mass of oxygen that has reacted if it is known that 35.5 g of phosphorus (V) oxide was obtained.
Given:
m (P2O5) = 35.5g
m (О2) -?
Solution:
4P + 5O2 = 2P2O5
n (P2O5) = 35.5 \ 142 = 0.25 mol
m (О2) = m \ M = 32 \ 0.625 = 20g
Answer: 20g
