Stoichiometry % Yields and Reactants
Can someone please help me? I've been trying to solve this since last night but my numbers are just so far.

Re: Stoichiometry % Yields and Reactants
For a) you calculate the mol of 405g PCl_{3} and according the equation you calculate how much Chlorine and phosphorous you need. Then you calculate the 100g P_{4} and 100 l Cl_{2} and compare. Dont forget the stiochometric factors.
n =m/M, n = mass/ molar mass.
b) is the difference of the theoretic and practical value.
c) similar, practical value of producct divided by theoretisc value of product
d) similar calculation with new values
e) dito
