The mass of P4O10 that will be obtained from the reaction of 1.33 gram of P4 and 5.07 of oxygen is
A). 2.05 gram
B). 3.05 gram
C). 4.05 gram
D). 5.05 gram
3.05 gram
Balanced chemical equation:
P4 + 5O2 --------> P4O10
1 mol 5 mol 1 mol
124g 160g 284g
Here limiting reagent is P4.
So, 124g of P4 produce P4O10 = 284g
Therefore,
1.33g of P4 produce P4O10 = (284/124)*1.33
= 3.05g
