So my test is tomorrrow, and I have troubles with limiting reagents, I can get them right sometimes with the 2 reactant questions, but not always with 3.... so the question is

Q: What mass of phosphorus (P_{4}) is produced when 41.5g of calcium phosphate, 26.5g of silicon diioxide, and 7.80g of carbon are reacted according to the eqation:

2Ca_{3}(PO_{4})_{2}+ 6SiO_{2}+ 10C -> P_{4}+ 6CaSiO_{3}+ 10CO

2. Relevant equations

n=m/M

3. The attempt at a solution

I've checked that the equation is balanced

and I calculated the moles of 2Ca_{3}(PO_{4})_{2}which is 0.1337 mols, 0.441 mols for 6SiO_{2}and 0.0649 mols for 10C.

after this idk what ratios to use to calculate what....
