Balance chemical equation.

P4 + 5 O2 -> P4O10,
1 mol 5 mol 1 mol.
124g 160g 284g.

Here limiting reagent is P4.
124g of P4 produce P4O10 = 284g.
So, 1.33g of P4 produce P4O10 = (284/124)*1.33 = 3.05g.

P4=124gm,5O2=160gm.
p4+5o2=p4o10
160gm.
124gm+160gm=284gm.
284\124*1.33gm=2.2903.
2.2903 * 1.33=3.0461.
And 3.05gm is the answer.
