Answer: 14.2 grams
Explanation:-
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the number of moles, we use the equation:
given mass of phosphorous (P) = 3.07 g
Molar mass of phosphorous (P) = 31 g/mol
Putting in the values we get:
given mass of oxygen = 6.09 g
Molar mass of oxygen = 32 g/mol
Putting in the values we get:
According to stoichiometry:
4 moles of phosphorous combine with 5 moles of oxygen
Thus 0.1 moles of phosphorous combine with = moles of oxygen
Thus phosphorous acts as limiting reagent as it limits the formation of product and oxygen is the excess reagent.
4 moles of phosphorous gives= 2 moles of
Thus 0.1 moles of phosphorous gives = moles of
mass of
Thus the theoretical yield of is 14.2 grams.
